[Q] Why are Nexus 10 handwriting apps always lagging? - Nexus 10 Q&A, Help & Troubleshooting

So I just bought a nexus 10 and among the many reasons for getting one, I want to take notes with it. I've bought myself a nice stylus that works wonderfully on iPads and my galaxy nexus phone. However, writing with the same stylus and exact same apps on my nexus 10 isn't working as one would hope. It seems to lag quite badly in picking up where my stylus is and this forces me to write very slowly so that it will pick up all of my strokes, thus making it pretty much useless in a classroom setting, but, like I said before, I don't see this at all with my galaxy nexus.
So, why am I seeing such a huge difference in performance between these two devices when (I assume) the nexus 10 would be so much more powerful than my phone? Is it the apps or the hardware? And how do I fix this issue without just writing my own note taking app?

I faced no problems working on freenote/ handwriting or myscript calculator ?? I might loook at the stylus and not the N10

But I've seen this issue regardless of the stylus used... Even with my finger I see a lag.
I also tried free note on my phone and tablet and am seeing a lag only on the nexus 10. I seriously doubt that it's the stylus, it seems to be isolated to my device...though, I haven't tried this with any other nexus 10 device. I don't know anyone else who has one.

a wild guess could be that the app aren't optimized for the high resolution screen and that is why they have trouble keeping up.
I haven't tried it myself yet but I will when I get my Nexus next week

Are you on stock? Or did you root and install a custom ROM? what about a custom kernel?
I have found some ROMs to have far more input lag than others, so that is why I am wondering.

I'm on stock everything. I am using Apex Launcher though.

Well stock should be ok. I see the most input lag with custom roms that do a lot to the framework and launcher, such as Paranoid Android.

I actually already saw that thread but thank you for pointing it out.
I haven't touched the Dev options and wouldn't even know how to change the magnification. I've only had the device for about a week or two and haven't had any time to really get playing with it yet.

I use lecturenotes from the play store, haven't had much of a lag issue
Using latest AOKP PUB build and Ktmanta
Also have force 2d GPU rendering on dev options

Just tried this with both lecture notes and free note (free note had less lag of the two from what I could tell)... It did improve the lag quite a bit, but I'm still seeing a noticeable and significant enough (in my opinion) lag. Seems that one step has been taken... Anybody got any others?
Also, I tried using Seeder but saw no significant difference on my device.
FYI, I'm now rooted but still using stock ROM/kernel.

Sorry about that, my lag seems very minimal, I've been taking notes in class all semester and it sends I've been able to take them quicker in my n10 then on paper, lol
I'm rooted running AOKP PUB 2/11 wit KTManta kernel (this setup, along with sine customizations to the kernel, have made my tablet really responsive and smooth)

I'm still having this problem on stock 4.2.2 (as well as the latest CM nightly), and was wondering if anyone had any fixes. My Jot Classic works okay, but not well enough for any serious note-taking, and considerably slower than the same app/stylus on my nexus 4 and 7. My main issue is that it isn't sensitive enough to write small exponents and subscripts.

Do you have force GPU rendering on in developer options? If so, turn that off, it got rid if my lag on lecturenotes after the 4.2.2 update

Today, I finally got my Nexus 10 and I started to investigate this ominous delay or lag. I indeed observe this lag on my Nexus 10 in LectureNotes and all other handwriting apps that I tested. As far as LectureNotes is concerned, I did a number of careful timing measurements and I think I can definitely exclude that the delay is due to slow drawing or anything like that. It seems that, on a Nexus 10, Android sends input events with a noticeable delay of around 250ms or so if they origin from touching the display, this is why a drawn line lags behind your stylus or finger. However, the delay is absent if you use a mouse (connected via Bluetooth), and hence there is no lag and the line follows the mouse pointer very closely. This is somewhat bad news, as this means that this problem cannot be solved within LectureNotes.

If that is the case, could the input delay be tweaked or removed through kernel modifications?

@EniGmA1987: If my explanation is correct and if one can modify the input handling, this might be possible. It seems that users with non-stock ROMS do not suffer from this problem, but this is just my impression based on contacts with LectureNotes' users and might be wrong.

Hey, I'm one of the people that has contacted you, and I can say that the input lag is significantly less on a custom ROM then on stock. Still there, but very slight

Sorry for not being more involved in this thread...been really busy lately.
I feel that have solved this issue for my current configuration. I've found that with the following setup, any lag that may be occurring is so slight that I either don't notice or I don't mind it:
-Get a stylus that actually works well (I had accidentally bought the first generation of the Adonit Jot Pro which has horrible sensitivity. However, after obtaining the 2nd generation, I've had no problems at all... one of my biggest reasons behind the lag was this 1st generation stylus)
-Stock 4.2.2
-Run Seeder 2.0
-DON'T force GPU handling
-Using LectureNotes Pro
-Create all lecture notes notebooks with a much higher resolution than what is initially set as the default. (This is what made the biggest difference)
From what I've observed, it seems to me that the best explanation behind any significant lag on this device is its extremely high resolution. I assume that most handwriting apps are programmed in such a way that the increase in pixel count hinders the sensitivity of the app itself.

[Q] Keyboard Lagginess on display units

I just got home from Best Buy where I played with their Xoom for about 20 minutes. Anytime I tried to use the keyboard (in the browser or just doing the google search on the home page), the keyboard only registered like 1/5 keystrokes I made. The line "just testing out this new xoom" would come out as "j tesgo t ewom" or something like that. I watched as I was typing and it looked like the keys were lighting up. Is this just a bad display unit or does the keyboard really suck this bad?
Let me put it this way, I am typing this on my xoom almost as fast as I can type on a computer. It does get laggy in the browser on more complex sites, but it shouldn't lead to that much mispelling. The keyboard is at least as good as the ipad in terms of speed.

Best Buy has some crappy units on display for some reason. ANGRY BIRDS lagged when I used the one at Best Buy.

The xda forum makes the browser lag like crazy, probably because of all the elements that are on the page at once. Use the xda app instead.
Not sure, but as far as my personal experience goes, every single floor unit of any device I've tried is always slower than the real thing. With the amount of abuse that the devices get, and in the case of Android the people messing with things that they don't know the reason for make everything laggy.
I remember using the Galaxy Tab at a T-mobile kiosk and having it run pretty smooth, then trying one in a Sprint store than absolutely lagged out and crashed several times. It really depends what people have been doing to them.
Let me also +1 the Xoom soft-keyboard- between the responsiveness and accuracy of the touchscreen, the size of the keys, and the medium autocorrect setting, what used to be a chore typing on soft keyboards has now made sending E-mails FAR easier (which my client certainly appreciates, as now I respond to E-mails coming thru in late at night or early AM much faster ).
I found that when I went to bestbuy the display unit was terrible because everyone installed apps and put a ton of widgets on the desktop. When I actually got my own xoom it was perfect and never had any issue browsing or using the keyboard. So I guess the point I am trying to make is that its more what people put on it then the unit itself and when you have tons of people messing with it a lot of things get screwed up.

The unit at the best buy I was at didn't have a google account tied to the device. You couldn't use the market, gmail or any google application. So nobody put extra apps or widgets on there. Maybe they messed with the settings? All I know is the keyboard was horrible. It would enter a couple letters, miss a couple letters. Half way through typing something it would auto-close the keyboard. Something must have been messed up, I guess. Otherwise I assume everybody would be complaining, which they aren't. I just wish I could have tested the device with the keyboard working correctly so I knew what to actual expect since I'm still on the fence between this and the ipad 2.
Sorry but its not the store unit's fault. This is something ive noticed and subsequently been annoyed with using my Xoom. Usually its while im using the keyboard in the browser window. It just cant keep up and misses keystrokes. It wouldnt be so bad if the keystrokes were just behind, but it lags enough where it doesnt even register some keystrokes. but like i said this is mainly in the browser. Plus for the person who mention Angry birds, i noticed this myself. Which is something thats alway bothered me about Non-Apple(dont shoot me im not a fanboy) hardware/software. If there was one thing i never experienced on my iphone/ipad it was subsequent slowdown while using apps and such. Everything was as quick the first time as it was the last time. Slowdown to me is a major nusiance becuase it seems to happen in intervals as apposed to consistantly. i hate that. Sometimes AB is smooth as silk other times its choppy, but i never know why or when.
I have noticed the lag too. Not on all sites but some especially XDA.I have seen many others complain about the same thing in other posts. Obviously an issue that needs to be corrected by Google in an update.
I have yet to see any lag playing Angry Birds.

Interesting since the unit I messed with had a ton of stuff. The only time I have noticed some keyboard lag occasionally was in the web browser when on some intensive websites but other than that seems to be fine. As a note you could try out a different keyboard on it if they actually have a Google account such as swift key and see if that helps. Also id see if you can go to another store such as Verizon and test it out there since normally it works well without lag for me.
That is very strange, I played with my new xoom and it was quick on all apps except for SBM but it makes sense since its not optimized yet but as far as browser and keyboard I haven't experienced any lag yet. Side note Google body was very underwhelming.... more for children then Med students or anything past high school.

My problems with the keyboard are how it freezes up during a keystroke and the only way to stop it is to turn the Xoom all the way off. It can be a bit laggy, but it seems to depend more on the app being used vs the keyboard its self.

Ya it probably depends on if the app is optimized yet for honeycomb so the keyboard lag issue should be fixed when everything becomes more compatible.

ICS Impressions, please share

Ok so for those that have been able to upgrade to ICS (P6800 owners) what are your toughts?
Now this is what i am looking for:
A) What you like
B) Don't like
C) What would you like to have seen included but wasn't (if anything)
And since having the update what are you looking forward to doing that you couldn't or wouldn't with HC.
Please don't post any issues you have after updating, that is not what this post is intended for.

Well i don't think that i don't like anything but i haven't really found something that is faulty. It is definitely faster as i immediately noticed that it took less ram, than honey comb, to run. Feels pretty fast with go launcher HD to me and i love it completely. Although i thought that there would be camera improvements as tab 2 7.0 has the same 3 mega pixel camera but does 1080p recording. So i thought that it might be done with tab 7.7 as well with an ics upgrade.

Well I love it to and made it up with Samsung:
- first with ICS that tablet really rocks it already did but now it's almost perfect
- smoother faster it seems especially the OOM killer seems more smart, and less memory used it seems
- no more problem with Itap rdp right click with bt mouse
- something I never mentioned. : I developed or try to develop a clone of pronto remote and debug using adb wireless
With HC I could not connect via adb on the computer using ethernet to adb wireless wifi due to packet loss... So had to disable ethernet and enable wifi. With ics no longer this issue...
- I used to have frequent sleep of death for the moment none
- I listen radio everyday through tunein somehow at around 1pm HC always rebooted by itself. Never bothered to figure out why... Now this no longer happen...
- no wifi issue ( some ICS user reported problems). I never had neither with HC except sleep of death or reboot that might be related to wifi?. I use Friztbox 7340 AP.
- my 100+ aps. Seems to all works (of course did not test deeply since yesterday) except gmd gesture control to hide the control bar
-once in a while but quite frequently using HC my EXCHANGE account would vanish...had to re-create every time... waiting to see on this one...Could be my remote application leaking....
So all in all very very happy with this tab and Samsung... Patience was what I missed
- I did wipe and did not have any problem if we refer to brick bug... But you never know...
What I like less
- dialog box theme gray without frame around
- it seems Samy addressed bur-in doing the bar black now....
I preferred it before and I don't have noticeable burn-in ( since march and extensive uses) except using color filter and brightness turned all down then I see slight yellow discoloration... Nothing to complain for me as the TAB HW screen etc are just so great IMO and outweight for me this small detail.
Seriously the TAB rocks for me...
Can you imagine 7.7 with quad core and dream about a 1080p SAMOLED display in a 7'7 TAB for me the perfect size!
I guess I continue buying Samsung.... Despite some of my previous comments... Waiting for the ICS on 8.9 now for my girl friend

My first impression
i installed the firmware through odin. it was not available on kies. so if i have to claim warranty ( god forbid ) then i guess i have to flash my country's HC firmware back
what i liked is that it is noticibly faster than HC. Apps load faster. lag is less. starting button lag is less. there have been no FC's and almost all of my games are compatible.
what i dislike or rather disappointed is that it does not look or feel much different than HC. no added functionality except Face unlock. what i would have liked is some features of S3.
i am running this for almost 24 hrs now. battery usage is same as HC.
I like that this device is actually usable now. I think I'm going to use it as my main tablet now. I didn't use it with HC because it was just so slow compared to my gt8.9 (running ICS rom).
My first impression: TouchWiz seems much smoother, Go Launcher HD feels the same. Under heavy usage of widgets TouchWiz is still great but Go Launcher HD not. I do love some Go Launcher features so I played around a lot and also tested the new 1.11 beta. But is still less responsive.
It's like a faulty motherboard replaced by a newer and faster one.
Seriously, like a new device, snappy, responsive, seems less battery hungry.
There is one 'custom rom" available, where EDaN has deodexed and removed some bloatware. I took that rom and took out everything social,photo and video editor, and some other minor crap.
Having 60 apps installed and tested it's like Christmas.
- dislike
had to discover I must install busybox to get Titanium working
had to install supersu myself, no biggy
no software based CWM, havent found compatible one, but one thats reboots to recovery anyway.
No powermenu at powerbutton
ugly blueish tint around quickmenu (with shortcuts for bt.wifi etc)
This all will be fixed when chefs get source or get impatient and offer CWM zips

my only gripe so far is that if you increase the font size to Large, some apps (mostly system apps) seem to have the font go to 'super large' e.g. google play, settings menu, whilst some apps its perfect.
Conversely, going down to medium, most apps are back to Honeycomb tiny font problem, whilst the system apps are fine
Seems like Sammy tweaked the touchwiz stock UI to display fine on medium size, without thinking that 'hey most apps the user will be using needs it set to large hmmmm'. Hoping AOSP ROMs will get around this issue
The tab is more responsive overall. Feels like a new device. But still not loving touchwiz--wish this is a pure Google device. Installing Nova Launcher partially fixes that. Only app not working out well so far is Battery Monitor Widget Pro--the mA usage keeps showing "0". Just about everything else survived the upgrade with no issues.
Add: mA information in Battery monitor widget works is set to "estimation" rather than automatic. So that problem is solved...
I never used tw always adw launcher ex on this device, everything is smoother with ics now we just need some custom roms and kernels so it can catch up to my galaxy note and asus prime

I'm truly loving this tab with ICS. One huge problem is with my WiFi. I experienced once again as it just disconnected and never connected again until I shut it down completely and turned it back on. Logged onto another AP. I hate this problem as I thought I had fixed it. It seems like the WiFi module is overheated and shutdown or something....*SIGH*

It's good stuff!
First: Hotmail seems to be staying put. Had big bothers with this as account would dissapear from tab. Seems to be fixed now, but need more time.
Second: SD Card behaving. Sweet.
Third: No waiting around for unlock screen to pop up when power button pressed. WTF was that anyway?
Fourth: Swype behaving itself. Kept on getting beeps before, and i would have to change to Samkey and back to swype. One crash so far in google translate.
Fifth: Browser no longer reloading all the time to homepage. seems more stable.
Sixth: Youtube actually responds when choosing a vid. If you hit back before and chose another, it was no longer responsive.
Seventh: AR much more responsive. 1sec response time. instead of 3-4. Overall response time much boosted. Has crossed the line from WTF? to hey... Sweet!
0'ed: Sammy did our super bloody expensive tab first. THANK YOU!
PS: flashed XL4 (United Arab Emirates) with Austrian version.(ODIN 1.85) Not a problem. Did Full Reset before flashing though. All went smooth. Im a very happy camper! Hope i could help.

stutter when scrolling slowly

I've noticed that when making a slow even scroll through any app the movement is kind of jittery/stuttery - kind of like a very rapid screen flicker (but different to the screen issues posted elsewhere as the brightness setting is not a factor). It doesn't happen on any of my other devices. Don't think it's a processor issue as games/videos are flawless. Has anyone else noticed this or is it just me?
On a side note, white backgrounds seem very yellow (see attachment) - especially compared to my OG transformer. It's not a massive issue and i appreciate this is a budget tablet - just wondering whether this is normal or if it's a fault.
thanks.

I notice this stutter in chrome all the time. Very frustrating.
I get stutter swiping from image to image in QuickPic, some microstuttering in Google+ in the What's Hot section.
Maybe some apps aren't GPU accelerated and the CPU is a bit on the poor side to handle it?

Have you also noticed that the yellow background is easier on the eyes? It was done on purpose, because this was built primarily as a kindle fire competitor..
As far as the scroll stutter, its Chrome. Try Opera or Dolphin and check back with us. It does the same on mine. Dolphin, Boat, and Opera are better browsers. Try them all out, I think you'll find happiness with one of those!

As i said, it's not specific to any particular app, it happens whether in maps, browser, menus etc. unfortunately.
Tried hw overlays; no joy i'm afraid.
This happens everywhere during any slow touchscreen movement because of a crappy touchscreen controller and crappy filtering algorithms. The app is just scrolling to wherever the touchscreen tells it to (which is to random points around your finger tip several times a second) and this makes it look like it's jumping up and down or microstuttering.

[Q] need some advice from everyone on my tablet.

Okay picked my tablet up two days ago from Walmart and I'm having issues.
1. Light bleeding in the right and lest lower corners (landscape mode)
2. Lag while scrolling in apps well choppynes. apps I know work fine they don't do it on my galaxy note 2 or my galaxy s2.
Could the lag issue be the cause of my tablet being on 4.2 so they are tuned for it? Would you guys be willing to test out alps I'm having issues with? I am rooted and have twrp installed I purchased my tablet from Walmart not sure if that matters don't know if they use inferior parts. Now would I return it keep I mean I mister have the best and when my 3 year old phone runs better on alpha there is a problem. Ate there roms to make it run better?

Not seeing those issues. I have tried several tablets over the past year and I am very satisfied with the performance and stability of this tablet See signature below for the rom I am running now. Even with stock there was no lag of any kind. Under the current rom and kernel performance is smooth and stable. I could try some apps for you.

If you can try the xda premium app as well as residentevil.net mobile app then scroll around in the dlc part
my nexus 10 has no light bleed, but it lags, occasionally. this is due to the super high res display. the tablet is pushing more pixels than it could, in the future though i think they'd release an update that further increases performance and optimizes apps to take advantage of that big display. hope this helps

Have xda premium. No lag whatsoever. Very smooth By comparison I had an Asus TF 700 and lag was a regular issue for the same reason the other poster to your question mentioned.
I have no problems with mine. Have you looked at Google Currents? See if the background sync is checked. I disabled mine after reading a bunch of posts regarding it.

Are we happy with the speed?

I'm just wondering what the general consensus was regarding the speed, the "snappiness" if you wil, of our rooted devices? I'm running the "unofficial" build of Carbon Rom on my HD+ and I think it runs pretty well. Def not as fast as a dedicated tablet but for a glorified e-reader, its not too shabby either.
I do need to be proactive with my usage of the unit of course, but I'm sure most of us here are. What I mean by that is that I do make sure I have as little as possible in terms of startup items (daemons) and run the occasional "fix permissions" or "clear cache"...
I've never tried a different rom besides Carbon, it was the first one I tried and I liked it enough that I kept it. For those that have tried others, do any run faster or smoother then Carbon rom? How is the state of the latest builds of Cyanogen 10.1?
Performance is sporadic. It is like something is in semi sleep mode at random points and the device has to wake up to get going again (this does not happen while using apps). Touch response is fine and the awful stutter (due in part to the constant library syncing) that the stock rom has is gone.
In spite of the lag, still works great. I am running into games that do not work that do on my other three Android devices, but again- we are probably using this device beyond the scope of its intent. The 4470 is a capable chipset, but something that goes beyond the 1080p display bottlenecks the device.
Perhaps the low ram (about 250 is allocated to the gpu) and the 1080p combine to be an issue that occasionally chokes the device- hence the lag. The T700 has a Tegra 3 that also has issues, but the increased the clock for both chipset and gpu to help offset the chipset limitations with 1080p.
Both the 4470 and Tegra 3 work fine with most 1080p video media, but pushing data to that many pixels is a much heavier resource issue.
Honestly I'm struggling with this quite a bit. I have an iPad 3 which is amazingly snappy on everything I throw at it, but I really prefer Android to iOS (I recently switched my handset from an iPhone 5 to a Galaxy S4 also) and the form factor of the HD+. However, I'm getting really frustrated with the intermittent lag on the HD+ with every ROM I've tried. It would almost be better if it lagged all the time because at least then I'd give up on it, but when it's not lagging, it's really an enjoyable device. But then it just starts lagging all of a sudden and I either reboot or go grab the iPad.
I understand that this device is resource constrained on both memory and GPU, but that still doesn't explain to me why it performs so smoothly sometimes and then lags other times until I restart it. I still think that there's some kind of resource leak or other type of bug that causes it to degrade into a bad state over time and that, once identified, will allow this device to be closer to what we're all wanting! Of course, that's also probably hopeful thinking...
My point exactly. The only common issue is the intermittent lag. I also have issues where it will freeze for over a minute and sometimes needs to have the power button held down to shut down and restart.
Becoming more a love hate relationship. Frankly were it not for the lovely display, I would have already returned it. I have the lag and occasional freeze is issues, regardless if a few apps or a lot of apps on the device. There is something apparently funky going on that causes the bottlenecks and occasional freezes.
Added: So far, more love than hate As far as the display, that is why I got the device in the first place, so would have not bought it without it.
I was having to many reboots and lag issues with CM10.1. then I flashed tweaked carbon rom and haven't had any issues at all. I have only had this tablet for about 4 days. This is day 2 with tweaked carbon rom. Love this tablet.
I had a Nook HD that was nearly flawless on CM 10.1. Two weeks ago, once the fire sale was on, I bought this HD+. I'm running CM 10.1 on emmc. I haven't tried Carbon yet! I haven't seen a lag issue but I do get the occasional soft reboot. I use my HD+ mainly for reading, and some light games. The HD is a little smoother, but I like the HD+'s size better. Besides, the display is great for reading. It is fast enough for what I use it for. The HD+ is an amazing deal for the price now. If speed was my ultimate concern, I'd be checking out that new Nexus 7.

I don't have an issue with lag myself. An occasional stutter if I have been using a CPU and memory intensive game and then switch to something else but that is it. Try Carbon it is pretty smooth.

Maybe android 4.3 will improve nook speeds with trim support. But I don't know if it just applies to nexus devices...
http://www.xda-developers.com/android/yet-another-reason-to-update-to-android-4-3-trim-support/
When I first started with my nook hd plus, the tablet was reasonably fast and had little lag. Now after 3-4 weeks it seems to be slowing down and lagging. I'm running the 7/19 cm 10.1 rom. Maybe a newer rom will help out. I haven't tried any other roms.

You guys might want to try lagfix https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix
I ran it and my nook seems to be a bit snappier.
When comparing benchmarks using Androbench https://play.google.com/store/apps/details?id=com.andromeda.androbench2 before and after it showed slightly better results too so it definitely does something.
This does the same thing as 4.3 when it comes to TRIM so its a good test to see what we can expect.

I can attest that this makes a BIG difference! I'd actually stopped using some apps because they now lagged so badly, Flipboard being a key example, but also Chrome (I'd gone back to the original Browser app). Immediately after having this run an fstrim, both of those apps are smooth again! I went ahead and bought the full version for $0.99 so that I can schedule this to run at 3AM every morning. As snargledorf mentions, this will be part of 4.3 so, assuming we do end up with a 4.3 ROM for the HD+, I'll be able to uninstall this app, but in the interim it seems to make a fairly significant difference along with some of the other tweaks I've picked up from the forums (disable zRam completely being a key one, perhaps also limiting the number of running apps to three).
Thanks much for the tip!

I downloaded this zram settings. How are you configuring it? If it makes the Nook HD+ better, I am all for it. So trying to follow some of the things you are doing.
Also I noticed that when I change the background process limit to 3, it changes back to standard limit when I reboot the tablet. Can I select the dont keep activities so it kills the app every time I close out?

I have zRam completely disabled. That definitely helped quite a bit. I haven't seen the background processes setting revert.

Ok, disabled the Zram. Do you need to do anything else with the program once you select that?

Funny, I just bought an iPad 3. With it jailbroken, it's pretty awesome and a lot of the tweaks feel native. I'm still holding onto my Nook HD+, though, for some kind of breakthrough that'll make it perform just as well as my Nexus 7.
Okay, here's how I have CM10.1 (8/1/13 build) on my HD+ configured now and I'm actually quite happy with the resulting experience:
LagFix – I set this to run automatically at 3AM every morning, and it has made the single biggest difference so far IMO.
Settings>Developer Options>Window Animation Scale/Transition Animation Scale/Animator Duration Scale – Either Off or .5x; I use .5x.
Settings>Performance>Processor>CPU Governor – Hotplug or interactive; I use hotplug. Make sure you check Set on boot.
Settings>Performance>I/O Scheduler>I/O Scheduler – Deadline or cfq; I use deadline. Again, make sure you check Set on boot.
Settings>Performance>Memory Management>zRam – Disabled.
Settings>Performance>16bit Transparency – Checked.
Settings>Performance>Surface Improvement – Fix color banding and blur effect.
I also set the LCD Density to 260 DPI since the screen’s physical density is 256 DPI. I use Build Prop Editor to change that setting and therefore have to change it every time I flash a new ROM. I've tried to put it into /data/local.prop and have it survive across flashes, but I haven’t yet had success doing so. Anyone have tips on how to do that successfully?
I'm curious to know if others are doing anything else to get an even better experience, and I'm also curious to know if these settings work well for others who are struggling with the lag issue.

To make the density in /data work, you need to use this command in local.prop:
qemu.sf.lcd_density=260
And the permissions on the local.prop file need to be set right. Make them the same as the build.prop file.

I have the same settings.
The one that made the major change is the Lagfix which transformed the general snappiness.
Though now i am worried by the warnings about potential bricking so am not doing it daily.
perhaps once a week.
Not at all sure if the other changes did anything.
Also what would be the advantage of changing lcd density (which I havent done)?
thank you for the suggestions in this thread. my Nook had become so slow as to be barely usable. I'll give these ideas a shot.
Tried Lagfix. Got my 1stCM stuck at bootanim. Scary. Luckily a 2nd boot worked...
