Zeam launcher + Universal Lagfix + tweaks + disable all animations = smooth as buttah

I own both as well. You can flash a custom ROM to the device with lots of the useless junk removed, and install a lag fix. Start with the FAQs on this site if you haven't already.
I must say though, I have never been so torn between two devices. I love the iPhone 4s stability and application quality. On the other hand, the SGS satisfies my primal need to mod and hack things. I also prefer the weight of the sgs. iPhone is a bit too heavy and fragile for my liking.

just install a custom ROM for your corresponding firmware and voodoo lagfix. done.
smooth and fast.
no need for taskkillers either.

The only thing that is (still) better on the iThing is the browser.

It its smooth because iOS implements hardware acceleration. It uses the graphics chip to render the animations, which makes everything seamless and smooth. This is easy because iOS is designed completely around around the iPhone. Android was designed for use in hundreds of devices with different hardware, so it does not use hardware acceleration (yet).

Well that is not the case completely. TouchWiz was indeed optimized for our graphics chip, however, without a lagfix, the access to the data is too slow and in froyo, the touchwiz launcher is too directly ported from the galaxy tab which causes our device to first render everything in 1024x600 and then scale down to 800x480 which costs a lot more resources than just rendering 800x480 or 960x640 (as on the iPhone). With the right mods, all this is corrected and you will find your SGS just as smooth as an iPhone 4. However all this requires a lot of reading and a significant amount of patience...
But It's definitely worth the reward.

Or we could wait for a:
-stable
-responsive-
-good battery life
-high performance (in addition to responsive)
-with all functions working
-with the original applications (Google and Samsung Apps)
-with the haptics
-long key press actions (menu/search, home/running apps, back/forceclose)
-sudo/root available
-apps2sd
-fully consistent user interface (with landscape mode)

Or we all could start mass complaint/class action against Samsung
This phone has been heavily advitised but does not work out of the box.
I received 1 offical update via Kies just after launch, phone went from totaly useless to usable to a degree. I updated to Froyo via reg hack and phone is better but still lags. GPS is still out. Battery life is still crap. Browsing crap, WiFi crap. Both were good on Eclair

Thats funny. Is there any device where someone hasnt brought up class action? Its like suing dodge cause they advertsed the 69 charger had big engine..but suspension and drag stunk... You could wait for the test drive results and dont buy one...unless you just think you have a right to have samsung make something better. i like mine. I also like finding improvements..sure.

I was going to question this and ask whether you were joking, but then I remembered this is Samsung, so it's probably true...
It's pretty tragic if that is what they're doing.

I think this is the same rant I see in all the posts about sgs, no point repeating in all the posts.

I am using launcher pro and so far, super satisfied with it. I am on stock JP6 Froyo and no Voodoo but still smooth as butter. I am amazed, I didn't turn off any effects.
Side by side to an iPhone 4, no problem beating the smooth game although iPhone seems more consistent. At some point though, launching apps or swiping from left to right seems faster on the SGS. No kidding.

[Q] Galaxy Note: The amount of its laggyness?

Hello Fellow Members,
Okay I have been reading a lot of complaints about the Note being laggy and frankly even I came across a couple of Galaxy Notes at two different malls/stores on display and they both lagged like anything. Although the lag was for just a couple of seconds but it was very frustrating. I noticed the lag throughout in the OS, right from swiping the home screens to scrolling in the settings or scrolling the browsing or while opening the apps. (Any app). And it became even more frustrating to see a previous model (Galaxy s2) working as smooth as melting butter. I operated them side by side and, man the difference was noticeable, seriously NOTICEABLE. I was soooooooooo disappointed. I had the cash with me but I was just not willing to believe, such a high spec’d phone would lag . And eventually I came from the store without purchasing one .
I have read on XDA forums also where many G-Note users have complained about their experiences of Galaxy Note being laggy. Hence, I would “request” you all to please make short videos of your galaxy Notes, upload on youtube and share the link with us here, so that someone who wants to buy a NOTE would see the amount of laggyness of the phone and then decide, whether this lag is acceptable or inacceptable for him/them. Please show the scrolling on contacts, S-pen notes, swiping between home screens, scrolling the browser etc.
Please guys, come forward and do so, as I youtubed a lot but couldn’t find videos showing the laggyness of Note. All videos are filled with how smooth and fast the NOTE is. And seeing that, I went to purchase one but….
P.S: Rooting isn’t an option for me as this will void the warranty and I don’t want to void my warranty. Hence no rooting
Also, people say that ICS will solve the issue. I have seen on other phones that initially it does make the device faster but with daily usage, it becomes same as it used to be with the previous version of OS.

Rooting will void your warranty but but if done in correct way you can unroot and get it back.
Older firmware were slow and laggy but LC1 and LC2 are smooth.
Have you tried V6 SuperCharger or ThunderBolt scripts before ? You'll need root though.
These littile thing inject steroids in your phone.

Wait wait wait wait.
You have used such difficult Jargons of Andriod world that I am just not able to catch you up .
Okay, as you have mentioned, V6 SuperCharger or ThunderBolt scripts will require Rooting my device (although I have no idea what are V6 SuperCharger or ThunderBolt scripts), but tell me these LC1 and LC2 are firmware updates, right? And they can be updated "without" rooting the device. Isn't it?
And this update will make G-Note blazing fast, like s2?

Guys, please respond and help.

Dont compare Note and S2. The same processor and same GPU in S2 powers a smaller screen with less pixels and less DPI. Here in Note you have the same processor and GPU power a huge HD screen with the best DPI in business. Also all the apps are built on hdpi resolution while the note is xhdpi resolution so the apps and launchers tend to get laggy. Also there is no hardware acceleration supported in much apps. I am using ICS Stunner and using it on 240 dpi which is hdpi resolution and its silk smooth. Butter!
And i dont have time to make videos. So if you can then take my word. If not then each one to his own
Cheers!! Enjoy your Note!!

You don't need to be rooted to update firmware.
Use pc odin or built-in OTA (Over The Air - Phone updates itself using 3G/WiFi) update feature.

update to the latest stock firmware released in 2012.....should b much smoother. But we're all waiting for ics which should be out very soon.
advice: go bak to the shop......remove all widgets on homescreen and/or change wallpaper to static nd try. I have noticed that some live wallpapers and widgets cause lagginess. I usually remove everythng from the homescreen and start adding them 1 by 1 and checkng.....one widget sometimes is the culprit.
Ics should smooth everythng as some have reported.

Owned a Note and 7.7
7.7 slightly slower than Nexus, Note is laggy, esp when not turned off for days.

I am not saying it should run games which require excellent acceleration or requires immense power from GPU, as I am not into heavy mobile games. All I require is butter smooth execution of day-to-day usage. Be it scrolling contact, scrolling web page, swiping through 10 application screens or swiping 7 home screens.

Your response is somewhat relieving I must tell you. But the comment under your post is disturbing . I mean I want a butter smooth tock ROM device and after paying $607 for G-Note, I don’t want to regret and speed it a “very” essential part of my checklist of a smart phone.

I never specifically told about games. To have everything buttery smooth u require hardware acceleration which gpu provides in the apps browser and launchers. So gpu is not just for games. Now you got why i told you all that above. To have everything running smooth on such big screen and resolution u require hardware acceleration. Ever noticed lag in all third party launchers? Its becoz they don't have hardware acceleration. The stock TW launcher is partially hw accelerated so still runs somewhat smooth.
The original dpi of Note is 321

Tbh you can't really blame the note for being a tad laggy since it is basically a computer and all computers ( even the best) will come across a type of lag within its lifetime.

Well then that sucks

here is a tip to the op.. You will find 99% of all problems you look for.. If you didnt look, you would not know there are problems.
The key to happiness in life is being happy with what you have and setting your expectations ot a reasonable level..
If you dont need the large screen, go buy something else. If you do need the large screen, then you have no choice but the note..
so either relax and enjoy your note or be paranoid about this and every other device on the planet, and buy every new device as it comes out and drive yourself into a frenzy of despair about this problem, that problem, this issue that issue until you realise all this agony and money has not fixed a single thing in your life, you are stressed, depressed and you end up a bankrupt nuerotic..

This device has NOTHING bad in it.. Just the LAG LAG LAG!
Nice post though! Loved it.

I am using stock GB and I have almost no lag. Maybe you should make a video and show us what lag you are talking about.

I am using stock rom (gingerbread) at the moment and experience none of the lag you refer to. I also tried some of the ics roms and also no lag.
The only time my phone 'hesitates' is sometimes when I unlock it as it switches from widget locker to lock screen. Now as it is a 3rd party app doing it, I can hardly blame the note. I love my note and even got rid of my galaxy nexus and asus tf101 when i got the note.

All I can think is, Gingerbread is just far inferior to ICS or Honeycomb. Nokia Lumia is a lot faster too (hope that word is not banned here)

Project Butter

Since the new 4.1 update will snap up the processor to max as soon as you touch the screen to keep everything running smooth, won't that take a larger toll on the battery than Android already does in general? Or do they have some new battery saving plans for this new feature.

I read somewhere that the JB update clocks the processor to a lower frequency when the load is low thus saving the battery.
I guess they compiled a new governor or something.

Yep

you guys don't know what projekt butter is?
they added a "tripple buffer for less locks and better process interoperatibility. one process doesn't have to wait for another anymore"
or in non dev words: they optimized the whole system
this doesn't has anything to do with the cpu freq.

Who gave you that idea? Not reading thread fully,i guess? We were not just discussing about Project Butter.We were discussing about how power efficient,smooth and fast the new update will be.And to further prove that the things we were discussing here is correct:
The first side of the Jelly Bean update is the way it interacts with hardware. One of the main complaints with Androids is that it often gets laggy even on the most sophisticated devices. Google has finally radically addressed this so manufacturers and developers can make their devices lag-free. The solution is called Project Butter and it comes with triple buffering so that the CPU and GPU work without waiting for each other. This means scrolling, zooming and virtually all actions become much faster.
Jelly Bean devices will actually anticipate where fingers are in screens which will results in a more responsive system.
The other big thing is power efficiency. Jelly Bean now dials the CPU back to lower frequency when it’s not in use.

BTW triple buffer,i guess you dont know what it is.
IN NON DEV WORD,optimizing touch screen drivers,GPU and CPU so that they work simultaneously,starting each process at the same time at the other.
@OP,google stated that as soon as u stop interaction with phone,cpu freq. will immediately decrease,thus saving battery.Somewhat like intellidemand gov.,but more seamless

Is Project Butter effective on the Galaxy Note?

Since Project Butter was announced as groundbreaking for Android devices, it would be good to know what the community thinks about it as the official JB ROMs have launched.
Please provide your input as a casual user and your day-to-day experience, and also as a more techie user or a developer.
The intent is to provide Samsung, if they still lurk on XDA, feedback on how they can improve future development to make Android really smooth, even though the UI is not treated with priority, as it is on iOS.
As far as I am concerned, I didn't notice any difference from ICS to JB on a stock ROM; essentially, Project Butter doesn't exist for my device. The device still stutters where it did on ICS.

I would agree with your assessment. I think that the stock JB is very stable, however there is no noticeable difference in speed compared with, say, LRQ.
When I press "contacts" or "phone" button, there is still a lag. My understanding of project butter (rightly or wrongly) was that these kind of lags are supposed to be almost eliminated.
Interestingly, when my wife's galaxy S was running slimbean 3.0, it was close to what I expected "project butter" to deliver. However I reverted her SGS back to ICS due to stability issues.
edit- I'm on LM5
edit 2 - Interesting that 90 people have viewed this thread so far, and nobody has disagreed with Incisivekeith's review. Perhaps we can conclude that "project butter" is not included in LSZ or LM5.

To my mind, Project Butter means an entirely GPU accelerated UI. That is what explain this "buttery" feeling when you drag down the notification bar, when you scroll in the browser, etc..
It is certainly activated in our JB roms, because if it was not the case, the rom would be much more laggier, and touch wiz would be the pain it has ever been since the Galaxy S.
However, I'm sure our PB is a far less efficient one than used in the nexii phones. You can easily tell, there are still some lag in the appearance of the notification bar (when opening an app, laoding something..), and the whole feeling is absolutely not like any Apple device (that I despise, of course ).
I have none of the technical skills to give a more detailed answer, but I remain amazed by the fact our devices are not free of any lag, in spite of their double core, big GPU, 1gb RAM etc...

To realize project butter you need a high speed camera. If you running heavily skinned OS has TW you will tend to see some lags. Remember Our note is almost year and half old....

Thanks for the link !
But we don't have the choice, i don't think any android AOSP/AOKP rom includes project butter, am I wrong ? These roms feel more laggy than any touchwiz rom, though they also feel lighter. And it's a shame (I blame samsung) because they are innovative and functionnal.

AW: Is Project Butter effective on the Galaxy Note?
As far as I understand, pb is not an acceleration for the hole system, but an acceleration for gui: no micro-lags in launcher, scrolling in Browser and apps. And it does really better, than ics for me. Just compare xda app on both systems and you'll understand what I mean

I tend to disagree on the part which states that these AOSP/AOKP ROMs feel more laggy than TW ROMs. As of today, I run Asylum ROM 25/02 which includes major improvements concerning the overall UI experience. It is snappy and smooth. I do explicitly avoid the term "buttery smooth" as it is misleading.
They are not finished products, that's for sure-but being heavily developed. :thumbup:
Any TW ROM running 4.1.2 won't be "buttery smooth" neither, whereas the leaked 4.2.1 ROM for the S3 already showed improvement and thus where helpful to update the Mali blobs for CM10.1, which are successfully implemented. They do work nicely!
If permitted to ask: when did you last try out an AOSP/CM ROM?
Side note: if you blame Samsung, you're always right! I fully agree.

I'd like to step in here, and this is entirely wrong: Project Butter was not included in jb for viewing in high speed cameras: it was mainly to reduce lag and stutteriness in Android to make the experience amazing for common, general public. Not for professional photographers.
Personally, when my one v is over clocked to 1.5 GHz and above ( and using a jelly bean ROM), the effect is mind blowing. I'd say the device comes near smooth as an iOS device, if not smoother. There are absolutely no lags and waits, and the device performs like a breeze.
Have you ever used a nexus device? That's the best implementation of a device blessed with project butter combined with the blessing of great developers of Google. I have not seen a nexus 4 lag ever. EVER.
Personally, I don't get what's it with galaxy note. I can't understand what's wrong with it to lag so much, I mean, sometimes it lags more than my one v which is a 1ghz single core processor ( I'm not talking about over clocking here).
I think only a professional dev can put light on this.

I totally agree with you, and the fact that an incredible amount of great work is put in AOSP roms remains undeniable. As I said, I blame Samsung, and my respect for developers is unbounded.
My last try was for beerbong's paranoid android v2.99, and I've tried almost any rom in the original dev section. Still, it's been a long time since I have tried, so i'll have a look ! Of course, there are other things that make me stick to stock, SPen integration mostly (looks like there is still no way to use palm rejection in CM roms).
Anyway, I'm glad to see JB leaks help CM developers, I thought the only workaround required kernel sources.
@soham_sss
I see I'm not the only one wondering what could prevent the note from being smooth...

For me, JB is very smooth. Don't forget, that our GNote has just that little Mali GPU which has to drive this huge 1280x800px (Macbooks of 2011 have this resolution ) screen. Based on that fact, JB is buttery smooth.
I suggest to set all animation times in the developer options of your phone to 0.5 (don't forget to reboot, to get the new speeds everywhere in the OS). It makes the Note feel much quicker and more responsive.
When you are there, also try "Force GPU rendering". Every app compiled with the 2.3 SDK has the GPU rendering flag set to off, this option forces it on. I haven't found any apps that don't like this setting and crash. Also, when you google for this, you won't find any apps neither that refuse to work.
I'm very happy with JB. It's smooth and the CPU doesn't have to render anything anymore. Nice!

As I'm thorough, I tried Asylum ROM, as advised. :silly: One thing immediately stroke me : the notification bar is not smooth. It just isn't, there's a discomfort that should not be as if it was still CPU run. And I don't think I'm picky, it's a raw feeling. The rest of the rom is, indeed, pretty snappy (the browser appear much much lighter), but I really need this element of my UI to be impeccable as it come to smoothness, just like the home screens transitions.

For me, JB is very smooth. Don't forget, that our GNote has just that little Adreno GPU which has to drive this huge 1280x800px (Macbooks of 2011 have this resolution ) screen. Based on that fact, JB is buttery smooth.
I suggest to set all animation times in the developer options of your phone to 0.5 (don't forget to reboot, to get the new speeds everywhere in the OS). It makes the Note feel much quicker and more responsive.
When you are there, also try "Force GPU rendering". Every app compiled with the 2.3 SDK has the GPU rendering flag set to off, this option forces it on. I haven't found any apps that don't like this setting and crash. Also, when you google for this, you won't find any apps neither that refuse to work.

I was not aware that the Note uses Adreno? I thought it was Mali

+1 couldnt agree more.
Ive always had nit picks with my android devices (mainly samsung, some HTC's in the past) and have always experienced some sort of lag, with stock and custom ROMs.
But, correct me if im wrong, I believe this is down to the overlay put on by these companies, they cram the devices with ridiculous amounts of bloatware and eye candy and I feel that has an effect on the overall smoothness.
Ive yet to own a pure AOSP device (such as the nexus's) but i cant recall many people complaining about them.
But I prefer the looks of TW / Sense over AOSP (and ive tried lots of AOSP ROMs) so I accept that bit of lag for the overall look and functionality of things.

Oops. I will change that. Nevertheless: That GPU just isn't the fastest anymore.
And that AOSP is faster, is just normal when you don't unbloat your phone. It's the same with every other Android phone out there. Also AOSP doesn't offer multiwindow, I bet many people aren't really aware of the technical difficulties this brings with it. And therefore this phone is very smooth.
Also try tinkering with the build.prop a little.
windowsmgr.max_events_per_sec
persist.sys.use_dithering
persist.sys.use_16bpp_alpha
can help a lot with the "lag".
But I don't have any lag, so I'm not changing anything. Another thing to maybe consider: Do you have a corrupt install?

The point of this thread is to discuss whether Project Butter is effective on the Note or not, WITHOUT any modifications.
4.1.2 JB LSZ Ultimate 5.2 ROM, KSO Modem, Phil's LSZ kernel, Carrier: AT&T (US)

It isn't since AFAIK Samsung doesn't release source code for Exynos.

If those on a TW JB ROM could download and install "Epic Citadel"(preferred via WiFi as it is a 150mb package) and play the demo. I bet it won't get beyond the 40fps in high quality..
I didn't advise to install Asylum and don't quite get the point of the notification bar. As long as Samsung fails to deliver "proper+sources" we won't get the real "butter" experience.
Apparently the leaked S3 ROM based on 4.2.1 went into a better direction as some Mali blobs could be used, but close to nothing from the 4.1.2 ROMs...
@incisivekeith It may be "project better", but not project butter.

All we need is the official source code and then everyone will be happy n_n

I'd like to step in here, and this is entirely wrong: Project Butter was not included in jb for viewing in high speed cameras: it was mainly to reduce lag and stutteriness in Android to make the experience amazing for common, general public. Not for professional photographers.
Personally, when my one v is over clocked to 1.5 GHz and above ( and using a jelly bean ROM), the effect is mind blowing. I'd say the device comes near smooth as an iOS device, if not smoother. There are absolutely no lags and waits, and the device performs like a breeze.
Have you ever used a nexus device? That's the best implementation of a device blessed with project butter combined with the blessing of great developers of Google. I have not seen a nexus 4 lag ever. EVER.
Personally, I don't get what's it with galaxy note. I can't understand what's wrong with it to lag so much, I mean, sometimes it lags more than my one v which is a 1ghz single core processor ( I'm not talking about over clocking here).
I think only a professional dev can put light on this.

First of all this is not one v thread or an iOS speed competition. Different devices get different sources to work with. So it doesnt mean that one v is superior. I am happy that at least cm team is giving us nice smooth, fast and daily ROM. TW is for noobs. I don't care about other devices or bull**** until I choose them personally. High speed camera was just for fun...
Cheers from Hell.... :sly:

once you remove bloatedstuff, like automated test, and about 30 others, own risk, reboot, flush cache/dalvik, you will notice considerable improvement, most of the time, but yeah it still stutters sometime.
damn endless tweaking, dont forget some to disable some triggers on boot fo apps you only need on demand.

[GUIDE] bcvictory's War On Lag

Hey XDA-ers!
BCVictory here! (Call me Bailey, my real name, if you want)
Ever since our beloved Nexus 7 came out there has been claims of people having problems with lag.
Especially since 4.2, the claim has gotten even more traction and it's more of an issue.
I'm here with some things you can do that may help fix/stop the lag.
But first, what is lag?
Lag is: Fall behind in movement, progress, or development; not keep pace with another or others.
So in Android the definition of that could mean: Falling behind in frame rate, not keeping up with or detecting your finger and not 'buttery' or 'smooth' (microstutters)
So now we know what lag is here is a few ways that people claim it stops/reduces the lag.
THIS ALL COULD BE PLACEBO!
ANDROID SETTINGS
Go into Settings
Under the System heading, go into 'About Tablet'
Tap 7 times on the Build Number
You should see Developer Options appear
In Developer Options
Turn these options on:
Disable HW Overlays
Force GPU Rendering
And change these options to either off or 0.5x
Window Animation Scale
Transition Animation Scale
Animator Duration Scale
APPS
Seeder
https://play.google.com/store/apps/details?id=com.lcis.seeder&hl=en
This app claims to:
Assist the kernel in "topping off" the entropy pool by re-seeding it with data from the non-blocking (high performance) random device. Optionally, it can also help alleviate MMC I/O contention by extending the I/O queue, allowing the I/O scheduler to make better decisions, and combine more writes.
On some devices, applications load significantly faster (particularly large ones like Facebook, Chrome, and Youtube), and task switching becomes effortless. Fewer visual "hiccups" occur.
Alot of the media and devs have said this app does not work but it does make this note:
This app does not increase raw performance, but rather eliminates some types of annoying lag (ie. applications briefly freezing, jerky scrolling, delays returning to the home screen, etc).
LagFix
https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix
LagFix is a user-friendly implementation of fstrim utility. It allows you to select which partitions to trim (you should leave defaults unless you know what you are doing) and run the process easily.
Forever Gone
This app will fill your SD Card with many blank files(*.blank), then delete all of the *.blank files.
One of the main 'fixes' people say to fix the N7 lag is to delete some files to make sure the storage has at least 2GB's free.
This app has helped fix lag that relates to this problem without having to delete those files.
Greenify
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
Greenify help you identify and put the bad behaving apps into hibernation when you are not using them, stop them from lagging and battery leeching, in an unique way!
This app helps reduce the amount of rouge apps in the background and save RAM. It's not like a normal Task Manager, It does it automatically.
Pimp My Rom
https://play.google.com/store/apps/details?id=com.androguide.pimpmyrom
http://forum.xda-developers.com/showthread.php?t=1908269
Pimp My Rom is an app that will allow you to choose between a plethora of tweaks, mods, hacks, features and apps to modify and improve your current rom. Pimp My Rom gives you alot of options to enable speed and battery saving tweaks therefore theoretically reducing lag.
FLASHABLE MODS / INIT.D SCRIPTS
Crossbreeder
http://forum.xda-developers.com/showthread.php?t=2113150
This is a new take at Android lag reduction. It's lightweight and won't consume battery. Users have reported drastic improvements in usability and even benchmark scores. It will show noticeable improvements on all Android devices from Donut to Froyo to Gingerbread to Honeycomb to ICS and Jellybean.
This is a combination of 5 different methodologies to reduce Android lag.
1. Removal of DNS lag
2. Change wakeup threshold kernel parameters so read blocks are released instantly and writes never wake up as we have an external entropy generator.
3. Modulate OS entropy levels for lag reduction. (Just like Seeder)
4. Remove /dev/random as it's blocking
5. Frandom support
Mitsuyoshi EXT4 Mod
http://forum.xda-developers.com/showthread.php?t=2280496
This removes the journal from all EXT4 partitions. This gives (on average) a 25% increase in system speed (due to the increased I/O rate)
V6 Supercharger
http://forum.xda-developers.com/showthread.php?t=991276
This claims to: Makes your phone/tablet FAST... super snappy with better multitasking! It rearranges and fixes the OOM Groupings and Priorites and lowmemorykiller values. So basically, it's a COMPLETE MEMORY MANAGEMENT FIX! NO LAUNCHER REDRAWS, faster than ever, multitasking is better... why? Because it works with the lowmemorykiller and letting it work the way it's meant to work.
Jay's Recipe for Buttery Goodness
http://forum.xda-developers.com/showthread.php?t=1946347
The script remounts /data and /cache with discard and noauto_da_alloc, disables fsync, enables a 128mb zRAM and set-ups a good, stable starting point for further modification. The result is a stable, considerably smoother multitasking powerhouse with overall better power management and performance.
INSTALL/CHANGE KERNEL - OVERCLOCKING
If you are running stock kernel or another kernel, it might be a good idea to try a new one.
One of these benefits is to overclock the CPU and/or GPU.
For my guide to the 'best' kernels for the Nexus 7 click here: N7 'Best' Kernel? (Performance & Battery Tests)
CHANGE LAUNCHER
If your launcher is the only thing that is lagging you might want to change it. There is a guide to the smoothest launchers at this link: http://forum.xda-developers.com/showthread.php?t=1899350
CHANGE ROM
If none of these tweaks aren't working or aren't enough for you, one of the last options is to change your ROM. There are lots of options out there so have a look around the Android Development and Original Development sections.
My personal favourites are Paranoid Android, P.A.C- Man, RasbeanJelly & SaberMod.
DOWNGRADE TO 4.1.x
If all of the above is not working try some of the older roms that use 4.1.x as their base.
WIPE EVERYTHING AND START FRESH
If absolutely nothing above works then it might be best to wipe everything and install a clean rom.
If any of these steps worked or didn't work for you, please vote in the poll above and also post below what did so you can help others.
If you find anything that helps or doesn't help reduce lag, please post it below.
If you found this helpful, give this post a thanks and give the people who made these tweaks a thanks too.

Thanks for the comprehensive guide!
Can't say I've seen any lag on my N7. Maybe something in this mix would actually increase the performance of my N7?
I'll have to sit back and wait for any recommendations that might improve performance. But thankfully, no lag here.

This is pretty frikkin detailed. Good job.

How about minimizing the number of apps that you have that run in the background and limit the number of widgets you have.
