[Q] performance cyanogen mod 7 nightly build

hey guys
Yesterday I switched from the HTC Stock rom to the nightly cyanogenmod 7, latest version as of today.
Now my question:
i have the feeling that the phone is a bit slow compared to the htc stock rom (of course I have activated USB Debugging). Now my question is if it is recommended to flash another kernel.
I experience the performance loss for example on the homescreen and in the app drawer, it just doesnt feel that smooth any more... which is strange because the cyanogen mod uses the adwlauncher and I had the same launcher on the stock rom, running very smoothly.
Now is it just my immagination or am I not the only one experiencing that "problem".
I appreciate any comments
greetings from switzerland

I'm on build 12 now and find it very fast and stable. I am using adw launcher without any lag. Did you do a complete wipe before the upgrade?
As for the kernel, these are currently no kernels that work for cm7, how ever the stock kernel is very good and will overclock to 1.5ghz if you want it to.

yes I did a full wipe of the data and the cache..
It's just strange because everything was running so smooth with the stock rom and adwlauncher or launcher Pro. I even flashed the stable versoin of cm... same thing there...

No I'm not using any of this stuff... I tried to sort out everything that may cause the performance drop but with no results..

What linpack and quadrant scores are you getting after a reboot? You should really run each one 3 times and take an average, this will let you know how slow it is (not a 100% test but it'll help)

Also might be worth having a look at "Power Tutor", it'll be able to tell you which programs are using the cpu the most, might find one that is hogging it for some reason.

How exactely do I get those scores?
//EDIT: Ok results: about 40 - 41 Mflops, Time ~2s, Norm Res 5.68, Precision 2.22etc

Have you tried downloading spare parts off the market and setting screen animations to fast, might be them that make it look like its running slower. Be Dr this I an running out off ideas, your score on Linpack is about right for a stock kernel, yet could try running setCPU and have the CPU running a little faster, I have mine running at 1.2ghz for day to day stuff.

If you are using apache14's kernel and use smartass that is your problem.If it's stock CM kernel I don't know...Try setting the governor to performance in setcpu and re-run the benchmarks.Telling us your kernel and CPU clock would help!

I have the stock kernel (as far as I know.. at least I didnt flash a new one... I just flashed the cyanogen mod) as far as the CPU goes: I dont use setcpu... how's the battery performance when u run it on 1.2 ghz?

I can usually get to the end of the day and still have about 30% left, but I an a heavy user and running the WiFi all evening, do a good 3-4 hours of browsing each day as well as other stuff.
This is not a problem for me as I charge every night. You should give it a go, if its no good return it to normal.

And you do experience a performance boost when overclocking it to 1,2 ghz?

Yes mate, I have a few profiles setup, when charging I have it set to 1.5ghz on performance, normal running is 1.2ghz on interactive and screen off set to 245mhz powersave. The phone is very fast, wakes up well and isn't doing to bad with the battery. The battery life will get better as the development of the Rom continues.

I just flashed the latest nightly build of 15 and it is just as fast as stock rom. Did not notice any slowness.

[Q] Any Mods/Methods to improve battery life on stock ICS?

I currently have Stock ICS and I notice battery isnt so good when compared to GB. Are there any mods to improve battery, cause I cant find any. Please reply and thanks in advance!

You can try Juice Defender or Tasker! Both of them can help you!

Does it actually work? Ive used Go PowerManager and the original Power Saver app for the device but it doesnt really work as expected.

i have stock ICS 4.0.4 (or arconium ICS) with KTG anzu kernel v1.41 and i get good battery life when using my phone
maybe go back to GB

Its all about usage, the best thing to do turn screen brightness down and turn off data and wifi.

As Smartarse93 said, it depends on the usage . With tasker you can reduce the usage automatically when you are not using your phone or when the screen is off!
Try tasker and see how it works!

[Q] processor keeps going above max cpu setting?

Hello, i am new to the android world, and am loving it. Ive tried a couple of roms, and decided to stick with Liquid Smooth Jelly Bean Rom. My only problem is this:
i have set the max frequency for the processor to be 1512 mhz(or lower sometimes), but sometimes it keeps automatically setting itself to 1900mhz, which i do not want. Is there a way to set it so that it will never go above 1512?
btw i am on 3.0.45 leanKernel if that helps.
Thanks

Check mark the set on boot box and restart phone right away after you change it back to 1500mhz.

Hello. So I tried this method and thought it worked.. but today while watching YouTube and texting it went up to 1900 again. I repeated the method a couple more times but it just maxes out all the time. Am I doing something wrong?
Thanks

are there any solutions to this?

Depends what kernel you're running, some kernel apps let you lock the frequencies so they cannot be changed by apps. If an app needs to run faster it will bump up the speed, so might want to check into that. Works on KT747 Kernel (Ktweaker).

Here's the link for the KT747 Kernel http://forum.xda-developers.com/showthread.php?t=1756776 . It works with all AOSP (CM10, AOKP etc.) aswell as most touchwiz roms. I've never used Liquidsmooth so Idk what it's about but this thread should contain information about which roms it is compatible with. If you have any questions I suggest starting a new thread about what its compatible with or asking directly in the thread. Good luck Always flash Rom before kernel.

Battery Undervolting

Hello, I just got a 2380mAh battery(brand new) When I tried charging it, it gives me 'Disconnect Battery error'. This did not happen with my stock battery. Can someone help me on setting up undervolting my battery and calibrating the right settings for my T989. I'm running on stock ROM and rooted. Any help would be greatly appreciated.

First ur going to need a kernel that supports undervolting, which means u need to flash Tiberius or go flash a custom ROM that allows it, then DL system tuner from play store and go to tweaks, find voltage control and undervolt till u feel comfy or it starts working better, don't go to low though cuz it'll cause bsods or rrs

Okay, thank you for your post, I will give this a shot and keep this post updated.

Good stable TW kernel?

My wife has a TMO S4 running Wicked V10, and it reboots often, I have tried Ktoonz kernel, I have tried Infamous Dev kernel, and all of them random reboot.
I would like to find a kernel that will be stable, but get her 4 hours screen on time IF possible.
Any recommendations?
Does she need to switch to AOSP/CM for something stable???
Any help is greatly appreciated!

People like the hacker 7 kernel.

Have you tried adjusting the settings in KTweaker? Not all devices react the same to the same kernel/settings.
Jovy's stock modified kernel is good too.

The Hacker v7 will be hard to come by as it's been removed from db's aroma installer. You'll have to find Aroma misc mod installer v6.

I thought the Hacker 7 kernel was for the international S4?
We can install it on the TMO S4?
I have adjusted settings in KTweaker, and no matter what I do, it still sometimes won't wake from deep sleep, or will Random Reboot at times.
The wife doesn't do much on her phone except read articles on the internet, and facebook, and pintrest.
She has become annoyed, which frustrates me, because I would take her to an AOSP ROM, but she NEEDS the TW features...LOL

I've ran Hacker v7 on Wicked v10 before with good result. I'm running it now with dbombROM. I have the M919 GS4 (T-mobile)

I've been running ktoonsez kernel ever since I got my s4. Only once was there a random reboot issue. I never have any issues with his kernels. To the op, the kernel is not always responsible for a reboot. You have to look at the last_kmsg in order to figure out if it was the kernel or not. But I love his kernel, great battery life and performance.

Just a heads up, there are development forums contianing roms and kernels outside of XDA.

Where can i get the hacker 7 kernel?. Can't seem to find it anywere
Sent from my SGH-M919 using XDA Premium 4 mobile app

I've flashed the mk2 baseband modem.bin file and flashed some 4.3 roms. tried several different kernels, ktoonz, modded stock and even a kernel from other forums. All of which gave Sleep of death issues and random reboots. I used suggested settings in ktweaker as well.
and before someone comes in and brings it up. Yes I always wipe everything before trying new roms, and I clear caches and fix permissions after kernels
I installed no 3rd party apps, ran the phone 100% stock (just with root) and it still happened. I'm also annoyed at the window transition animation always reverting back to 1x after setting it to "off"
Ultimately I went back to 4.2.2, cuz I can't really see a difference between 4.2.2 and 4.3 other than moving apps to sd, I don't even know what all exactly was changed besides that and the notification bar being transparent now. Is there a list of "whats new" in 4.3 somewhere?

Unless you can find an older version of db's Aroma misc mod installer, it's not available anymore.

Like roms, all are best and all are stable, the answer to this can only be determined by the individual user based on their needs and desires.
As XDA is not a support site, please take the time to read the products offered in development sections and figure this out on your own.
