Improving performance by removing virtual keyboard

My biggest problem with G1 is not having enough ram. While checking what sits in my ram with MemoryUsage app I noticed virtual keyboard. Since I almost never used it, I killed it. This caused home to reload, but I believe that keyboard has not been loaded instantly.
But after some time, I could see it there again hogging my precious 9MB. Since my phone has usually only like 15MB ram free, this was quite annoying.
After doing some research and BACKUP, since I am rooted I decided to rename the application to see if it will work. The app in question is LatinIME.apk. I renamed it to LatinIME.apkBkp. While I have been there, I did the same thing with LatinImeTutorial.apk. Both files are located in /system/app.
You have to remount it writable first, search this forum for how to do it.
After renaming that file (and maybe killing the app, don't remember exactly) my phone tried to reload home. It failed to do so, force closed and then tried again, resulting in infinite loop.
I rebooted the phone and it worked well, starting normally. Now I have more ram and performance of my phone improved a bit. My free ram stays a bit higher and apps are not so often removed from it.
Overall I am happy about the result and I am looking for more unnecessary stuff to remove.
I am on CyanogenMod 4 btw., so there might be different keyboard apps on other roms.
I have not found anyone mentioning this here, only some tutorials how to change default keyboard, so hopefully someone will find this useful.
If you have any suggestion how to sqeeze even more ram from my G1, bring them on please. (I know of swap, compcache, 10mb hack and keeping low number of apps)

Unused RAM is wasted RAM. The system will kill applications when more memory is needed. Don't worry about it.
And time for you to upgrade to CM6, don't you think?

Idiocy runs rampant at Dream forums, huh? Blame the stupid Advanced Task killer dev for getting all these idiots believing killing apps actually serves a purpose...
Anyway, if the OP is concerned about memory usage and bloat, I very much doubt CM6 is a step in the right direction. Maybe the latest CM 5 is a better option.

Yep, I am very well aware how does it work, but killing the app and loading the other one uses CPU cycles and makes system slow. Especially if it happens all the time as it does on my phone. This is actually the biggest source of laggines imho.
Plus, I am pretty sure, that system apps are not unloaded (some of them at least) or they are unloaded as a last resort. Which was also the case here. I could see other apps being killed (which I did not wanted to be killed) while unused virtual keyboard was happily sitting there.
For the record, I do not use task killer of any sort, does not make significant difference for me and occupies more ram than it saves. So please save that 'idiot' for someone else.
I do not plan to switch to CM5 or CM6, because those need even more ram as CM4 does. Afaik, those roms use hw graphics support which prohibits 10mb hack. I definitely keep 10mb hack on my phone. Did a lot of good to it's speed.

Okay so what setup are you using?
I have tryed every which rom out there since i got into it and i usually only use my phone for browsing youtube music and normal phone stuff and am find these new firmwares to be getting sluggish. Basically i want a lightning quick basic build. I am interested in what exactly you are using.

I am using last version of CyanogenMod from 4 series. That is Android 1.6 based.
I have apps2sd, 10mb hack and compcache enabled. No swap. Was not working for me. I removed all the apps that stay in memory like all widgets etc. The only things that is running in my memory permanently are: SeePU (to monitor my phone), JuiceDefender (to save battery), Battery Left widget and Astrid.
I set my phone to keep Home app in memory all the time, removed all the unnecessary effects in Spare Parts and removed virtual keyboard.
With this setup, my phone performs quite ok. Not as snappy as I would want it to be, but acceptable.
Hope it helps.

I have been using Super-D 1.9.3 with 10mb hack. Removed VPN, VoiceDialer, GenieWidget and some other misc things. Latest ADW instead of Launcher.apk, MusicMod 1.5 instead of stock music, latest 1.6 Phone.apk from Wysie. I also themed my lockscreen and Powertop widget. I has been about 4 months since I flashed it and it hasn't slowed down much at all (and I rarely reboot it). Not a singel FC! Battery lasts me thru the day (I have facebook, twitter and Gmail updating themselves). All in all, its one of the best set-ups I've used. I strongly suggest trying out earlier Super-D roms if you're looking for reliable daily driver (anything before 1.11 should be quite good, 1.11 is when it all went downhill)
Good luck.

You have options.
-Remove apps2sd and use the mtd patch method. That way you cut out the slowest link on the phone: the memory card. With the MTD hack, you can get maybe 150 megs or more of internal space for apps on a donut rom.
-Use the latest version of setcpu since it doesn't stay in memory. You can try an overclock, it will help but shorten battery life some. Maybe 576 or 595 would be enough of an overclock to make it feel faster yet not drain battery like crazy.
-Keep CC on and lock home in memory
-remove the battery widget lol.
=Delete juicedefender and just use the power control widget.
-I usually remove apps that tend to launch on their own, such as the genie widget or the voice search, as well the the VK since I never use those. It's easy enough to write a script or remove them by hand from the terminal. for example, to remove the VK, open terminal and type
Code:
su
mount -o rw,remount /system
rm -f /system/app/LatinIME.apk
-reboot your phone often, and try clearing your cache using cachemate or similar

*** Galaxy Tab Master Tweak Thread***

Hi everyone.
Id like to start a thread where we collect, post and discuss all known individual tweaks and changes that can be made to the Galaxy Tab in order to gain performance and stability.
My experience with the Galaxy Tab has been similar to my latest phone, an HTC HD2. When I got the HD2 about one year ago, I positively hated it... slow, unstable, all sorts of problems, lags, crashes... its the way most of the hardware today is released. One year later, my HD2 has become the most amazing machine I've ever owned. From pushing it 1.6GHz stable, to tweaking registry, XML files, services and making everything work well. I remember not being able to watch smooth video on the HD2 to being able to watch flawlessly 720p content and going from the extreme of detesting the phone to loving it.
It was with the HD2 I discovered Android and fell in love with it. Since I have now two HD2s I have one with an SD ROM version of Gingerbread (that I can dual boot still from Windows Mobile) and a Froyo NAND. I run Android on the HD2 much much much faster and smoother than on the Galaxy Tab, that I also hated when I bought it a few weeks and that am starting to like after getting to know it, a new ROM, apps, etc. Even at 1GHz stock the HD2 with Froyo is vastly faster, smoother, more responsive and better to use. The approach d like to do as far as tweaking the Galaxy Tab is the same as I did for the HD2 with Windows Mobile, that is, install the best/fastest ROM I can, delete and remove all stuff I don't need and then tweak what's left.
The tweaks I've done so far on the Galaxy are simple but have made a huge difference. Id like with this thread to be able to collect individual tweaks and post them all here to share with everyone.
Im using Roto JMI Pre-Rooted Firmware v2 which was the main step after getting rid of the stock Samsung Rom that is nothing but a collection of problems.
The first thing I learned with this Tab is that WHATEVER IS ON YOUR HOME SCREENS THAT MOVES, IS BAD! Forget about having ANY type of apps or widgets that do any type of refresh, including stuff running on the upper task bar if they change icons or the move around… that mean a CPU cycle and refresh each time and there goes the tab's performance and battery life. The same goes for any type of Live Wallpaper. Beautiful but deadly. Never touch them!
- So, after a new ROM, the first thing I did was changing the file system to EXT4. This is the SINGLE BEST THING you can do to radically improve the performance of the Tab. Its extremely easy to do and the step-by-step instructions are as follow:
- Make sure you have an miniSD Card in with plenty of available space (it will be used automatically to backup your system during the conversion process)
- Get p1000-mck-r3-ext4-cwm.tar (the EXT4 Conversion Kernel)
- Connect the Tab in Downloading Mode to your PC via USB, start Odin3 1.7 and load the Kernel (click on the PDA button and select the p1000-mck-r3-ext4-cwm.tar and make sure PDA stays ticked after selecting the file).
- UNTICK Re-Partition check box and make sure the only boxes ticked are:
Auto Reboot
F. Reset Time
The PDA tickbox
- Click start and wait for PASS! (it will show highlighted green or Yellow on Odin)
- Now the Tab will restart and get stuck on the Samsung loading screen. This is normal. Turn it off by holding the power button for 5 seconds.
- Turn on the Tab again on into RECOVERY mode (Press Volume UP and Power On at the same time) and the EXT4 conversion will start automatically. The process will take up to one hour depending on how much stuff you have on your Tab. It took about 10 minutes on mine because I have a fresh install of Roto JMI v2.
- Once finished, click "Reboot System Now" (by pressing the power button).
- The reboot may take a while first time so be patient!
- Done!
- After that, the first tweak I did was to get rid of all my favorite widgets that moved around… net meter, news, weather and all these beautiful things KILL the Tab. Equally I had a CPU meter on the tray refreshing every 2 seconds and it took me a while to figure out that was the reason why every 2 seconds the system would stutter, whether watching a movie or browsing the web. So, out!
- Next was to install SetCPU under the ON DEMAND setting, minimum around 750MHz and maximum 1000MHz (unfortunately only with a custom Kernel you can go higher, currently up to 1.4GHz but not full stable and with lots of issues pending so I don’t recommend it)
- My following step was to get rid of the stock Samsung Homescreen (that is a resource hog and slow as hell) and replace it with a new one. I've tried them all and am making no recommendation here but the one that works for me and is by far the best IMO is LauncherPro. This single app makes using the Tab a whole better experience.
- Next was to disable the USELESS and (resource pig) Gallery and replace it with an app called QuickPic that is blazing fast (actually instant) and simply amazing to browse and view all media on the Tab.
- Next was to greatly improve the poor native GPS reception by replacing high performance files and drivers from the Orange Rom P1000JHKA1 that seems to work on all versions of the Tab, as originally posted here:
http://forum.xda-developers.com/showthread.php?t=922692
- With SystemApp Remover 4.12 I have disabled all system apps and services I don’t need (BE VERY CAREFUL AND DON'T REMOVE ROM APPS YOU WILL NEED). I have actually deleted some from ROM (Root access required of course), this includes useless stuff like STK Service starting every time, most of the Samsung stuff that I really don’t care for and just about all apps I know for sure I will never open a single time. Now, its important to understand if these apps are removed they will be removed PERMANENTLY from ROM so to get the back a hard reset will not be enough, you'll have to fully flash the ROM again. For most system apps I don’t use but am not sure, I use a different option and that is to simply disable them. In my case this includes all Bluetooth stuff (I never use it and even if it's off the Services are still running robbing performance and memory) and apps like the built-in Browser, Email and Messaging that suck and that I replaced with better apps. Its always a safer bet, at least initially to disable the apps you don’t need that uninstall them because at least you can go back and change your mind This is one area where Id like to learn more. There are many background services that I don’t know what they do and if they can be disabled or not. If someone knows what each one does and the safety of getting rid of them OR NOT, it would be great to post it here!
- Them, with Startup Auditor 2.3.2 I have disabled all unnecessary apps that start automatically every time the Tab boots so I don't have excess applications starting up that are not needed. Some I configured to be killed AGAIN if the system tries to restart them later after the boot-up
- Using Task Manager 1.0.7 and letting always run on background, I have configured all apps that I don’t need running to be auto-killed every time the phone goes to stand-by (screen off). This saves me lots of memory and CPU time on apps that I am actually not using.
- Finally, I monitor what is going on with an app called CPU Usage Timeliness Free 1.7.1.0 and use it to see EXACTLY which applications are using CPU cycles and interfering with performance. With it I have found that on my Tab I have an unsolved problem that is using over 100MB of memory and non-stop CPU usage between 15% and 45% of something called SECURITY STORAGE. I have no idea what it does. It can't be disabled and I don’t know where all the activity comes from. If someone know more about this and how to fix it, that will be great. Most of the performance issues I have on my Tab come from this Service that I don’t know how to tame. Surely, we can find a solution.
The system background services is one area where I'd like to know one by one, what each service does and if we need them or not, if it can be tweaked, disabled or deleted. Below is a complete list of the services I have safely disabled so far that have given me great performance boosts and with no negative issues on the system (IN BOLD), and OTHERS I WOULD LIKE TO KNOW MORE ABOUT (not bold). Please note these are background services that start automatically. The changes made to the disabled apps/services is that they are reverted to ON-DEMAND so they all still work perfectly.

Originally with my Tab I was getting Quadrant below 600 on average. Now, its always over 1900. This is not a "little" improvement, this is amazing upgrading. But id like this to be a starting point to learn and share more ways with everyone we can all share on things we can do to make the Tab as good as it was intended to be for everyone
Cheers!

1.4 oc is stable, and doesn't have any issues for alot of users.
all the things you disabled are all the things i use every day lol
never the less, good post, im going to use a couple apps you mentioned.

The first block of disabled items (in bold) from CALENDAR to WORLD CLOCK are disabled start-ups but the apps works as usual. It just frees resources not required on boot till you actually start the application when you want.
The second block from Bluetooth Services to Voice Search are all disabled as I use none of those. Items disabled can be restarted again at any time upon activating them follwing a reboot, while items deleted (like Samsung Apps and STK) are gone forever.
Ive never flashed a ModaCo Kernel and got lots of feedback regarding probelms with 1.4OC. Do you have any issues at all or none? We are using different ROMs... What Quadrant do you get currently?
Cheers

Thank you for your post.
You have solved many of my questions. Also I am User of HD2 and had the same impressions, but now with Android Nand everything was great, also started to love it.
As for GTAB'll make those adjustments you suggested, some will not disable because I use Bluetooth as an example.
Any news please keep posting.
Success!

So far the oc is good, things load a little faster, especially nfs shift. Last run of quadrant was 2300-2400.
Ill try it again later after these optimizations and see how it goes, a member here has gotten 3000.

Having done nothing but root, my tab gets about 1000 quadrant score. I have tried setcpu using on demand and it actuall has made my tab worse. I am very hesitant to flash anything on the tab. It seems very involved and complicated. I have an HD2 as well and have been flashing since Android was on SD. That process is simple. Everything I have read about flashing things to the tab doesn't look that way. I really havent had any issues with my tab as stock other than a bit laggy at times. I would like to hear more about all of this. The oppinions I have read are either do it or don't do it. There are more problem posts after attempting to flash than there are good ones where it worked. I really could care less about a quadrant score to be honest, but I would like to have a faster smoother running tab. I really dont care about making calls on it either. Thats why I have a phone. JMO. I think part of the issue in this thread is that there are Euro and USA version which are completely different and require different roms and such.
I have been reading and lurking in the tab development thread for a while now and am not impressed with any of it yet. Maybe someone could shed some light on things and change my mind.

I agree. The process of flashing the Galaxy is much more dauting than anything on the HD2. I suggest you do the EXT4 file converstion. All you need is follow the step by step I wrote above. It makes a huge difference. As for everything else, I too hold off to do too much flashing. The ROM I use now is great and lighter than stock but your seems to work well so keep it. For me when a ROM is good I just use it. When I bought the HD2 I flashed it 2 times with a custom ROM till i found one that worked for me and kept it for 8 months. But backing up and restoring WinMo is much easier... on Androind its all more complicated if you dont know what you are doing. Disable some start-ups on your unit, convert the file system to EXT4 and make sure you have nothing on your home screen doing a lot of refreshing and your tab will work great

Is everything working 100% on that ROM? I do not want any ROMS that are having problems.

I too am not impressed with anything that us out yet...seems like any ROM process is tedious and complicated.
Glad the thread starter modified his tab to his liking, but what's the point of having it if you need to drastically change everything. I have a rooted DInc and not use any of things......didn't really see a performance gain with set CPU.
I'm going to continue waiting for something more reliable and use my tab the way it was meant to be, with all its hardware and widgets.

Thank you for your detailed post. While I agree with you that the stock SGT rom and browser suck but where do you think the JMI, JMF, JMx ROMs coming from?
Most ROMs I've seen (except for CM) are based from some sort of Jxx
Please keep the tweak posts going. Good stuff and thanks!

Not impressed with all the problems being posted just tring to flash it, and how complex it is to do it. Guess that's what I meant. Flashing the hd2 is a very simple process. Tab is not
Sent from my HTC HD2 using XDA App

My boy,
Only getting my Galaxy tomorrow but looking through threads on my favorite forum.
And guess the first one I happen into... I will follow avidly.

Hi dubie76,
Try an app called OCLF 2.0 on the Market. It is a Lag fix app for the Samsung Galaxy S which also works on the Tab.
https://market.android.com/details?id=com.rc.QuickFixLagFixR2
You have to install EXT2 tools and then install one click lag fix, both are done within the app.
I had this on my Tab before flashed to a custom ROM. The tab was much faster and did not have and lag compared to stock, the Quadrant score was around 1900.
Also you can uninstall the modifications in the app and easily reverse back to stock. The only disadvantage is you will loss about 800mb of internal memory (the 2Gb space), so if you don't have much space left, you will need to uninstall some apps and reinstall them once you applied the lag fix.
P.S. thanks to OP for the SystemApp Remover & Startup Auditor suggestion.

Custom ROMs?
Hi everyone!
Consider this:
The locked GTab (in standby) on an original ROM with a connected to it BT headset wakes up after replying a call from BT and can potentially have anything pressed as being in the bag due to its size...
My point is that there is NO fix for this on XDA therefore why should I expect any significant advancements from a custom ROM if such simple things cannot be fixed on Android.
My personal view is that Android is unfortunatelly not as flexible for adjustments as WinMo (i have HD2 as well with a wonderful custom Artemis ROM).
I've tried two Roto ROMs on my GT and they havent provided any noticeable enhancements in performance to my eye (perhaps some rating went up - I dont care about tech stats). I reverted to stock ROM P1000XWJMI that works as fast for a "regular user".
I am sad to resume my experience with hacking the GT as not worth it: you get serious risk of getting the GT bricked (much more complicated than with WinMo), loose the warranty and are open for instability and sudden incompatibilities with crashes.
On the third custom ROM installation attempt I was stuck on a black screen after powering on (stuck on the bootloader!) and couldnt initiate flash for multiple times. I was shocked and very nervous. Thats when the stock ROM saved my ass and I am not willing the risk of playing around any more with non-firmware ROMs for Android GT.
Regarding the alternative screen lockers available - please do not suggest Screen Suite (the best of the worst) and things like No-Lock (to get rid of the original locker) as they all mess up once in a while (tested) with the default ROM settings and the original core locker.
PS
In my view the best thing we can and should do first of all is to COMPLAIN to SAMSUNG Tech Support and Software Developers (I did twice already).
If every one of us from theese GTab forums would do this they would definitely get faster with resolving issues.

My point is that there is NO fix for this on XDA therefore why should I expect any significant advancements from a custom ROM if such simple things cannot be fixed on Android.
My personal view is that Android is unfortunatelly not as flexible for adjustments as WinMo (i have HD2 as well with a wonderful custom Artemis ROM).
I've tried two Roto ROMs on my GT and they havent provided any noticeable enhancements in performance to my eye (perhaps some rating went up - I dont care about tech stats). I reverted to stock ROM P1000XWJMI that works as fast for a "regular user".
I am sad to resume my experience with hacking the GT as not worth it: you get serious risk of getting the GT bricked (much more complicated than with WinMo), loose the warranty and are open for instability and sudden incompatibilities with crashes.
On the third custom ROM installation attempt I was stuck on a black screen after powering on (stuck on the bootloader!) and couldnt initiate flash for multiple times. I was shocked and very nervous. Thats when the stock ROM saved my ass and I am not willing the risk of playing around any more with non-firmware ROMs for Android GT.
Regarding the alternative screen lockers available - please do not suggest Screen Suite (the best of the worst) and things like No-Lock (to get rid of the original locker) as they all mess up once in a while (tested) with the default ROM settings and the original core locker.
PS
In my view the best thing we can and should do first of all is to COMPLAIN to SAMSUNG Tech Support and Software Developers (I did twice already).
If every one of us from theese GTab forums would do this they would definitely get faster with resolving issues.

So what if the screen goes on in your bag, unless you have a fresh finger floating around in there nothing can press any buttons on the capcitive screen, also my tab I just hit the lock button in a bt call, screen turns off phone stays on

troubleshooting a slow G1

I rooted my phone a few months back and it's slow switching between a few screens, mostly from calling or web browsing back to home. Painfully slow, sometimes up to a minute. It's always been like this and I just want to know if there's steps I can take to speed it up or if it's just a memory problem. I used Cyanogen 6.1 to upgrade to android 2.2.1
Baseband62.505.20.17u_2.22.19.26I
Kernel 2.6.35-9cyanogenmod [email protected]#2
Build number - FRG83

G1's are just slow!
Try keeping it lite. Uninstalling apps, keeping the essential ones, app2sd?
Don't have loads of widgets on your homescreen.
Task manager, i recommend ATK.
Hope this helps.

If you are up to it, flash different ROM. There are ROM out there that is lightweight and fast. My personal favorites is SuperAosp. Currently they just released SuperAosp 6.0 that is fast and also best on bettery life.

Well, it's slow compared to what's out there, but it isn't "one minute to switch apps" slow for me... without a task manager or auto-killer. Every time I wipe I install nine apps from Market, and ten from SD card. They may sit back and be inactive if I've opened them, but they don't just all run at once and slow down to "one minute each switch"...
I'd agree with the widgets on homescreen though. I tend to avoid them out of preference, but they 'can' eat memory faster than we can down a beer. I don't have anything locked in memory except Messaging. Depending on what I'm switching from, it doesn't usually take that long to switch. If it's something like Skyfire -then no matter what I'm doing, the G1 just dies and Skyfire force closes pretty quickly. It just cannot handle such a memory hog. If I play SNesoid, I never see a force close and it takes seconds to switch. I don't fully understand it, but consider how resource heavy your apps are.

Seems to me you have swap enabled and now it's swapping ...
Try to run without swap / compcache and see if this helps.

Reducing the widgets helped a lot. It's very usable now until I need to upgrade to 4G. Thanks for the recommendation. What is swap enabled?

Might I recommend trying a different ROM? On my Samsung Vibrant, I had stock TouchWiz and it went slow as hell, I tried another custom ROM and it works great. Much much MUCH faster, trust me get a different ROM, ask around for the best most light weight one, Super AOSP w what someone recommended here? Try that.

Def check froyobylazlo 5.2 you'll need the new radio/spl hack by ezterry but its soo worth it. Auto memory manager helps out greatly too cuz its based off androids internal tasker instead of just another program made from someone else. With that app your g1 will fly even on default settings, on extreme....lol thank me later

My G1 got slower recently, but not one minute slower. I've been really good about not installing anything except I configured titanium backup to run automatically, but the home screen has been crashing a lot too for some reason.
All I did was create three shortcuts for calling and texting someone. Those aren't the same as widgets are they?

Hero very slow;Is this normal?

Hi all!
I currently have elelinux 2.1 ROM, but I think that's not the problem, because with others rom is very slow too.
For example, when I'm writing a text message, on twitter or whatever, sometimes it has a delay of 1 second more or less, activating 3G/wifi is slow as **** too. Even turning screen on and navigating through desktops or apps is slow. When I call, it has a delay of 3 seconds before it appears on the screen. I can't even listen to music because the phone get stucks... I could give you more examples, but I think is enough to know that my hero works to slow.
But I don't know if this is normal or not, I don't know other people who own a Hero.
Thanks in advance

Yeah it's an outdated slow phone really. I would consider it normal.

Maybe you have some apps installed and running in background? Try to install fresh ROM or uninstall all applications and try then.

are you using an thirth party keyboard like better keyboard?
those are a bit laggy somethimes and that can cause your 1 or 2 seconds lag
and maybe try to flash a new kernel (like this one http://forum.xda-developers.com/showthread.php?t=730471) or start again from scratch

Hi!
Recently I've installed Thumb Keyboard, but the keyboard was laggy before that, so that's not the main problem I think...
I know it's an old phone, but this slowness, it's unbearable... and my contract doesn't end until october >_<

instal a task manager maybe?
or delete your phones cache (can be done by apps in the market)
otherwise.. i dont know whats the problem
i recomend a radio and kernel update (can be found here on the forums)

Yes, try a task killer to find out what processes use phone memory the most.
Kill them periodically, or just uninstall them if it's not necessary.

hi everyone
i think that's the steps of solving the problem try it
1- if your memory card is full try to delete anything you not use in it.
2- make a Swap partition and that's the link > http://forum.xda-developers.com/showpost.php?p=6907762&postcount=47
3- install fresh rom for my advise (VillainROM-v13)
4- install task killer that's help phone to be faster
now your phone is fast!! enjoy

You may wanna consider overclocking a bit. That's helps my phone quite a bit.

may be you've to reflash ROM
i usually flash ROM every 3 months

Solution without Sense:
go and get elelinux 2.8 ROM
OC your cpu (needs root and care not every phone can handle the highest values, ele has included oc app in his rom)
find the lowest working freq without the phone always restarting itself
find the highest freq without stability issues or overheat
after done this, check "set on boot"
switch all animations off
install just the apps you really need
remove all that unnessecary junk from your homescreen, a clock widget (example beautiful widgets lite, weather animations off, free from market) and some shortcuts are enough, if u want u can keep search widget
play around with cyano settings so you get optimum results
then your phone should not show too many lags, at least mine does not.
Solution with Sense:
Go and get a fresh rom,
example
elelinux repacked 2.1 rom,
VR 13 (also 2.1),
SalsaSense (2.3.3, not as fast as RUU 2.1 though, and use Las Venturas 0.4.7 kernel)
Same procedure as above: OC, for me i use 264-768.8MHz and ondemand gov
Remove all that unnessecary htc homescreen junk like music widget , peoples widget, weather.....
if u want you can keep htc clock widget, but do animations off
Phone should be FAST!
greets, S.O.D.

id recommend updating from 2.1 to the 2.8 version. the set the cpu to 176/652.
then install task manager. this should sort all your problems out

try overclocking the phone, i use floyo rom and it run so fast for me

was using villainrom 12 and recently shifted to villainrom 13. trust me it is the best rom i have ever had. i use taskiller with it and my phone simply flies. though battery remains an issue. i am using the stock keyboard and also the stock sms app. would suggest all to give it a try (those who haven't)

I too have had a slow hero and it is definately not rom.
I actually had 2 heroes , One got rooted on day and has been ok .
The other ( nephew was using it) was slow and I always assumed it was his stock system, unrooted setup.
When I got the phone back last week, I rooted it , put a few roms on , wiped everything that looked wipable in recovery , put in a new sd card , setup a app2sd partition ( using rom manager ) .
and still its deadly slow.
If it was a PC I would think its faulty memory so only the good portion is working but I have no way of checking. ( unless you tell me)
also the apps2sd might not have taken as i tried to format the partition after creating it and it couldn't find it.
any ideas?

Things to get sense 3.5 running smoother

Just trying my best to help out! These are the things i do to improve performance on my hd2 (tmous) running sense 3.5. Some of these are risky so read before applying
1. Swap.
There is much of debate about using swap on your android device,some say its useless and it wears down the sd card and others say it speeds up your device on a notable level. What i've noticed is that swap behaves according to what else is using the sd on android at the time, remember that android is also accessing the fat32 and your ext4 partitions. Right now im not using my ext4 partition on my sd and and i can notice the little boost from swap , and on the previous rom which ext4 was needed, using swap would more show up on benchmark than actually being experienced.
HOW TO GET SWAP WORKING. Its very easy on the sense 3.5 roms!!!! Just partition your sd using recovery in magldr, download script manager from the market and download swap-hard.sh from Dorimanx's high performance rom.
in script manager go to where u downloaded the script and run it (run as root and run at boot). Thats it!
2. VM heap size.
i set mine to 96m ,using blade buddy from the market. In advanced settings edit the value in dalvik.vm.heapsize press menu save and restart.(dont overdo it 96 already is.
3. Overclock. I just overclock to 1.382Ghz max 576 min with the performance governor. (please read about the dangers of overclocking your hd2 before choosing to do so.)
4. v6 supercharger. Search for it, read the thread!!! use and enjoy!
5. Reduce system traffic. As wonderful as the hd2 is we need to remember that it has its limits no matter the os u put on it (lack of speed, heating up, speedy discharges ect). this is all due to what im calling system traffic, the autosync every 10 minutes, the running 10 apps you dont need just because, things like that. These things unbalance the performance vs the productivity. Set the auto sync to an hour or take it off . close apps when u r done with them. Clean up the temp files regularly (caches ect).
6.Flash the newest radio Leo_RADIO_2.15.50.14
This is it for now if u got anything else to help then please reply as these things can help any rom , also u shall take full responsibility for any future damage to your phone or phones hardware (nothing to be scared about but im putting it up incase.) And it would be great to get a dev's opinion on this and to also correct or guide people to better settings.
i would love to post a video but i have a dell streak 7 and the vid recording is horrid!!! but the average quadrant is in the 1200s.
