Hi all,
I've been running DKstunna's CM9 global rom with aeroeven's v14 kernel for a few weeks now. It's a great stable ICS rom that makes for a great daily driver.
My question is if anyone has tips to make the phone snappier. For example, if I hit the search button, it takes a full 4 or 5 seconds before google now comes up. Another example, if I'm installing an app, there is significant slowdown all over the place.
I know I'm working with a phone a few generations old, but does anyone have tips to make the phone snappier? I'm open to everything, including flashing new roms, new kernels, etc. All I'd be wary of is flashing roms that would decrease phone stability.
BTW I did a search! but didn't see anything.

You probably didn't know what to search for...hence the results. You need to look for overclocking, cpu governors, minfree settings, zip align, and there are others that speed up your phone.
First: under performance settings, what max cpu frequency do you have it checked as? And what governor are you using - I personally like smartassv2.
Second: try a different kernel if you have already overclocked and set the governor.
Third: try a script like v6 supercharger. There are a lot of them that take care of some of the above mentioned stuff for you.

Thanks for all this! You are correct, I clearly had no idea what to look for.
My min cpu frequency is 245 mhz, max is 1024 mhz. The governor is smartassv2 - it must have flashed along with another rom/kernel I may have tried in the past.

Hey guys, I was looking at flashing a cm9 rom, just for fun, and on the rootzwiki page, it does not show a kernel to flash along with the rom and gapps. I just want to make sure that there is no kernel, or for someone to direct me to where the kernel is, just to avoid anything going wrong.
Thanks.

Aeroevan made a kernel that allows extra governors and the ability to underclock. I posted a link in the ICS thread in the general section for Inc2 here.
Thanks for the quick reply, another question though.
You said something about the smartassv2, and good battery life in the same sentence. What is smartassv2, how much does it improve battery life, and how can i get it/flash it?

SmartassV2 governor improves battery by sitting on the lowest possible cpu speed when you have it sleeping and then only uses the amount of cpu necessary for your phone to run smooth when you have it awake. So if it's set to say 1.3ghz, which is what my max cpu is oc'd to, then it will run at that speed when it needs to but fluctuate between my lowest setting and that in order to conserve battery use. When you use that along with incredicontrol app to undervolt your cpu it improves your battery drastically.
I have my settings as so:
SetCPU: Max CPU: 1305600 (1.3ghz), Min CPU: 245760 (245mhz) using smartassV2 governor.
Incredicontrol: -25 across the board, this is done by clicking the back button on the top of the app one time, which sets all of the frequencies -25 at once.
hmmm... I'm looking at your sig, and if im flashing between roms, and not flashing radios, do I need to worry about what radio I'm on? I just read that it is very important not to downgrade your radio, but I have no idea how I would do that...

The radio is a seperate flash that is not necessary for the OS to run a certain way. You can try out different radios if you like. I have the newest because it gives me the best Data and Voice signals in my area. Different radios give better reception for people depending on where in the U.S. they are located. If you have a good clear signal you can choose to stay on what you have, I'm assuming you have the .722 radio. It doesn't hurt to try others though, worse case scenario you get no signal and have to flash the previous radio back again. Just make sure you are installing the correct radio for the Inc2 and OS. The GB radios work fine with ICS.
My phone freezes just as or very soon after i choose to overclock in cm7 settings.
My last WFS was really loving the O/C.
Has anyone any solution. Many thanks
Edit: I can use userspace govenor and go to 806mhz but dont notice any difference in speed of hone. Tried cpu spy
Perhaps it's your kernel. Which kernel do you use? (go to Settings, About Phone, Software, More, Kernel version)
Also, what apps do you use to do the overclock?
It's likely your phone. Not all chips are made the same. Set your governor to performance and slowly ramp her up till it freezes. Then take a step down and leave it.

Hi guys,
I'm a bit of a noob so please bear with me. I recently rooted my phone (SGH-I747M Telus), I have CWM recovery installed. I was interested in overclocking so I installed this kernel on my stock rooted rom (I installed the "sammy" one). I also cleared the delvik cache, cache, and fixed permissions before rebooting. Now I'm having a weird problem with video playback. I get these bleep like sounds, like you might hear on a spaceship, lol. The normal audio plays in addition to these sounds. Yet, regular audio plays fine (mp3s), same with youtube. So, my question is, why? Is there any way of fixing this? I'd rather not play around the stock ROM. I made a backup before doing anything and recently tried to restore the boot, but I got an invalid md5 check.
-JC
Okay, I was able to fix my problem by flashing the stock at&t kernel... but I would still like to be able to overclock... is there another kernel that I can try or a way to fix the problem with the kernel I already tried? Thanks.
If you still want to try previous kernel your problem might be because of heavy undervolting , kernel creator posted this voltage chart.
You can experiment by increasing voltage and see if that helps.
Or you can just try this faux kernel , its pretty good also, we don't have many kernel choices for Samsung based roms at this early development cycle.

Thanks for the reply... but I was able to fix the problem. It was something wrong with the settings of SetCPU which I installed earlier. I changed it from on demand to performance and now all is well. Now I have a question about battery life. Will overclocking drain battery a lot faster? I imagine it would only make a difference if I was doing CPU intensive things.

Well.. performance setting makes it so that your CPU runs 100% all the time. I don't think that will be battery friendly . Overclock generally uses more power and battery longevity will depend on your usage.
You can try messing with setcpu settings. Try Conservative, then limit minimum speed to 384 and max to your preference. Try your movie again.
Current kernels and setcpu are a bit quirky.
I had the same issues on ktoonsez Sammy. Ended up back at stock AT&T. I've heard it's an issue with many of the kernels but a fix is on the way. Couldn't find a way to get rid of it, but that's not to say it can't be done. Don't have much time to tinker right now.

Its a known issue on ktoonsez kernel. Flash faux's kernel, it has the same features (as well as GPU OC) and doesn't have the audio issue.
Hy all,
I'm running JB Sourcery V5.1 (latest) and I had some trouble wih the speed.
The ROM comes with it's own kernel, it allows me to overclock my GNex to 1.4 GHz top (screen attached).
I ran a Benchmark and poor results. See from the screen, the results are lower than what a Gnex should be !
I tried to flash Franco Kernel but the device won't reboot, it stays on "Google" and never starts the bootanimation (i had to do a wipe to make it boot).
So if you are on JBSourcery, is there a way to overclock it more than 1.4 GHz ?
Why does the Franco Kernel block the boot ?
Not every Kernel can be flashed on every ROM ?
Thanks for the answers like always !
I managed to make the franco kernel work.
There's a section in the JBSourcery tools dedicated to kernels. This ROM is amazing really.
Anyway, thanks i guess ^^

As you can see in the Quadrant screenshot, the I/O Performance probably is the problem. Wich I/O scheduler do you use?
I'll check the scheduler settings.

Hy,
The settings are :
Read ahead buffer size : 1024
Scheduler : deadline
I never touched these so I don't really know what there here for ...
You base your performance based on a number spit out from Quadrant...
Here's a novel thought: How does it actually work for you? Are you having problems with it lagging during certain operations?
Yea, Cilrazz is right. If your system is smooth you shouldn't care about the Quadrant results at all.
To answer your other questions:
a) You can not use every Kernel with every ROM, there migth be some incompatibilities.
b) If you want to overclock more than 1.4GHz, you'll need another ROM, wich allows that. But you probably won't need that for smoothness or performance during standard use. In fact a lot of people have underclocked their CPU's to 10.6GHz and the GNex is still more than fast enough for everyday use, while saving a lot of battery with this lower voltage.
c) concerning the I/O sheduler. wich schedulers do you have available, maybe another than deadline does work better for you (personaly 'fiops' works best for me) ...ah and I'm pretty sure, you should set the read ahead buffer size to aprox. 2048 for better performance.
d) I don't know whats your exact problem with the franco Kernel. Have you tried a clean flash? (means: wipe cache+dalvik, factory reset, format system, install ROM, kernel, GApps, wipe cache+dalvik) -- ! make a backup first, you will loose your settings, when resetting to factory and loose your app and app data on format system !
Ah and i'm pretty new here too, so be carefull not everything i'm saying is 100% right. :fingers-crossed:

The benchmark results were only here to show the lack of speed that i had. But i really had speed trouble and i couldnt screen that ^^
But now it's all good. Thanks for the answer tho'

Hey,
Thanks for the big answer mate.
I'll try to answer step by step
B/ I did manage to flash the Franco kernel but using the download kernel feature in the settings (maybe a special version). The over clocking is for the gaming actually like Modern Combat, but the device becomes hot as the sun ! (Not good).
C/ I never touched the I/O zone. It works pretty fine this way so I won't mess with that ^^
Thanks for the answer tho'. Very much appreciated!
I have been using Omega Rom from version 8 up to version 18, then switched to ProBam, then Pacman, and now I'm back on Omega 19, giving the "official" 4.3 a shot.
I have tried many many settings and kernels to get this game run without a lag.
So far, I have seen no lag when using performance governor while playing for a few minutes (no overclocking the CPU or GPU) that was it...
Every other setup gives lag, more or less. The second best setup would be pegasusq governor, not much changes when overclocking CPU or GPU, or both.
Using a stock kernel is also not bad, but lags every now and then. (not dependant on Rom)
But I want to get the sound settings from trickster mod for example, so I feel like I need a custom kernel with my Rom of choice.
So, does anyone have a good setup that matches performance governor, but does not stick permanently to maximum CPU load?
I don't care about battery life, so I need a good performing setup.
(Just on a side note: when people say "there is no lag at all when scrolling through my homescreens" then I can only think that this should be normal with ANY setup. And I never had any lag while scrolling through my homescreens, except while I was using my HTC Hero...)
I would very much appreciate if someone with the same goal could help me out, or someone knows the default settings of the stock kernel...
Or is this whole idea just utopic, because the game is badly coded?
