I've loaded my TyTN II down with many applications and enhancements (thanks largely to this community), and while the configuration is just about perfect for what I want, I've found that performance can get unacceptably slow in some (not obviously reproducible) situations. Things like selecting a soft-key button, opening a window, ect can sometimes be very slow now.
Rather than uninstall/test/reinstall everything, I'd like to find a way to identify what processes are consuming what resources over time. RAM is fairly straightforward, but I've never seen an instance where reported program RAM had less than 40MB free, so I would assume thats not the issue.
Does anyone know of an application that can show (or better, record over time) CPU usage by all processes on the device? Can anyone reccomend other ways to "debug" intermitting performance problems?
Thanks! -james
MemMaid is one program that can show you CPU usage by processes. I don't believe it will "record" usage.
which is the better option for performance (with respect to speed and multitasking)
As I understand it zRam compresses unused apps within the system RAM. So there is a CPU cost as well as reduced available RAM for other apps.
Swap files don't restrict available RAM but writing to the sdcard impacts the speed of opening apps.
Can both be used at the same time? I don't think so, but maybe I'm wrong. And perhaps using both has a negative impact on performance.
If only one is a viable option, which one should I use?
for me swap is better
Hello all, today I will be showing you how to speed up your Nook Color a bit... these methods should work for CM9/CM10/CM10.1/Paranoid Android/etc., but I personally found these out while running PA ICS. The apps you may need to make your phone faster are Ram Manager (Free OR Pro) and No Frills CPU Control (In the case that your ROM doesn't have overclocking in settings). Basically, using these "tweaks" (minus overclock, as whenever I flash a ROM the first thing I do is overclock it), I went from a painfully slow (as in, I was ready to go back to Gingerbread) device to a somewhat faster device. I've seen huge differences in launching games and apps especially, and opening to app drawer seems to be smoother also.
CPU Overclock
Either using No Frills CPU Control or the built-in overclock, set your max CPU speed to the highest on the list (not exceeding 1200, but it shouldn't show anything above that anyhow). Change your governor to either Ondemand or Performance (I personally use Ondemand and have no problems with it). Most of you are probably already overclocked though, so please don't look at me like I'm stupid.
Swap Space
Open up RAM Manager and there should be an option to change your swap space at the bottom. I changed mine to about 48 and am content with that, although I must add it may make your SD card's life shorter. This will increase your RAM, thus allowing you to have more apps open at once.
Force GPU rendering
Open Developer Options in your settings app and check "Force GPU Rendering"... I'm guessing this is one of the biggest factors to my tablet becoming smoother, as from research it helps lower end devices achieve a better framerate, although it may decrease your battery life. Also, I cannot guarantee every app will run great with this. I tested a game (Dynamite Jack) with this setting enabled and it wasn't too shabby at all! But yes, I can definitely see a difference in the overall speed of my Nook Color.
Please tell me how these work for you
I tried these settings, but unfortunately didn't perceive any performance improvement.
Good call on RAM manager. Hadn't seen that before, its going on my NC and RAZR now
Can anyone tell me a good reason for that RAM Manager app to have the permissions it does? Location, Identity, and full network access?
Does NOT work. All this app " no frills CPU" does is provide a GUI front end for the settings already found for our nook color using CM 10+ in its "performace" settings. Also this app does not provide over clocking above our set 1100 MHz. You will need a custom over clocking kernel for the encore for this. Check over on the CM 10 kernel thread n the development section.
Hi guys!
I'm on eXistenZ 3.0, and everything's perfect, but i wanted to know how can i use the 'overclocking' settings? Do you know an optimal frequency?
Or what exactly can i do with that?
I'm just curious

Interesting that you should ask. Coming from windows/intel chips, where overclocking is going beyond the highest value set at the PC bios to speed up the computer (thus generating more heat), I come to understand that "overclocking" in the android world is either to increase the lowest setting or decrease the highest setting for optimal performance (basically to save battery or reduce heat). In android, there is no way to increase the set highest value that I can see...
Of course, I stand to be corrected by long time android users here (I just came into android in Feb this year)

Do you want to Overclock the SoC itself or tweak the other options such as the Low Memory Killer, SD Card Read Ahead, etc?
Since I'm running the stock kernel (my bootloader is relocked), I cannot overclock the SoC
I usually use:
Governor: ondemand
I/O Scheduler: deadline
But
Governor: interactive
I/O Scheduler: deadline
Would sometimes deliver higher benchmark scores
With regards to the Low Memory Killer, I'm satisfied with the stock settings but try to experiment with the other presets as you please.
As with the SD Card Read Ahead, I've selected 2048kb as it is said to be the optimal value. You can try to use benchmarks to determine what works best with your sd card.

Also, if you really want to overclock your SoC; you can choose to unlock your bootloader and flash DoomLord's DoomKernel. :3
Remember to backup your TA Partition first before doing this step as unlocking your bootloader WILL cause you to lose DRM Keys (bye bye Bravia Engine 2 and Download Music Info). You can search for BackupTA 9.10.
DoomKernel allows you to overclock up to 1.8GHz, provides you with a plethora of Governors, Schedulers, and other performance enhancements. e.g. Samsung exFAT Driver, etc.

I see - there is a real 'overclocking' after all...
Thanks.
Everything is a bit new to me, new android user too. (i'm on locked bootloader)
Yeah i saw that i can maximize the current minimal settings, and minimize the maximum settings. I tried to increase a bit the minimum settings and did a benchmark, and i saw a difference already (i did 384 MHZ --> 584MHZ). But i dont want my phone to overheat or to decrease battery life.
The other options, i must admit i dont understand a thing, so what do you suggest to improve battery life for example, (or optimal settings if there are)?

I would suggest:
Min: 384
Max: 1512
Governor: ondemand
Scheduler: noop
SD Card Read Ahead: 2048kb
As for the other settings, it's better to leave them untouched.
For additional battery saving,
Install "Greenify" to hibernate power hungry bg apps such as facebook.
Also, turn off location services and auto-sync if you don't utilize them.
You can also go further by using "BetterBatteryStats" to monitor which apps are sucking your battery.

THanks a lot dude, i'm gonna try it!
btw if i set max to 1512 Mhz, my performance (while gaming for example) will decrease right?

Yes. But it shouldn't be that much.
Using noop as your I/O Scheduler results to faster SD Card Reads while reducing CPU Cycles, reducing battery drain. Reduced CPU Cycles would seem to affect performance though.

No problem. Just click thanks.
am using "rom tool box" on my XSP (rooted, .201, stock rom, c5303)... when setting up CPU speed, after reboot, settings are back to standard?!
any idea why'S that, or is it normal?

Check out for other apps or init.d scripts that may have configured Processor settings during boot time.

sry, but, how to do that Oo
Hello! I recently installed the reyzen kernel on my cell phone, and I have a good kernel manager on my cell. I learned a lot, but there is still something I can not clearly understand: Low memory killer (LMK). when I want more performance on my mobile in a game for example, should I increase or lower the LMk values? Here's an image to show by example what I'm talking about:

for example, if I want all aplocativos in the background not to be executed, should I reduce or increase this value?
