I also get poor performance when all tweaks are enabled. Maybe thats because some of the tweaks is for better battery life and therefore lowering the performance. This is why I have asked for a detailed list of all the tweaks and what they do, but I have only recieved info on the RAM management tweaks. I really would like to know what all the rest of the tweaks does, so that I may choose the performance/battery enhancement that works best for me.

Laststufo your kernel is very fast. I liked your kernel very much. But in the previous post i have said that NFS shift is crashing after the initial splash screen.But since other users reported that the game is working fine in their mobile, i uninstalled the game, wiped the cache and dalvik cache. But sadly the game is still crashing after resinstalling.

Please tell me what to do as the game works when i use any other kernel.

Besides this small thing, this kernel is very nice. i love the speed of this kernel. Please dont take it otherwise, i am just flashing every kernel and testing the performance of games. I just want to get help.

Once again thanks for giving such a smooth and fast kernel.

I would be fairly sure that the exact values are different though.

I have had "inconsistent UUID" (amongst other) errors with JFS too. I have previously avoided Ext4 because of the high battery usage, for no apparent gain (in fact, maybe a little worse); however, I have been on Ext4 with 'unsafe mount options' since this afternoon and I am finding the battery drain only tiny bit worse and the performance a tiny bit better. I am not sure how stable it is, but can be no worse than my record with JFS. Worth a go!

VSF Battery drain test

@laststufo:

I had a feeling that VSF on doesn't drain battery less, so i made the following test:

- set the screen to never turn off

- set the brightness to 0

- during test selected homescreen (to have same colours)

- didn't use the device

VSF enabled:

i got a battery drain of 9% in 62min

i noticed that the screen flickers really much without doing anything

VSF disabled:

i got a battery drain of 9% in 65min

So i think VSF enabled may even use more battery. Is it possible to change screen fps related to cpu clockspeed?

Best Kernel

Hi Lastufo, I'm from Verona too. I hope that you'll never drop this project, because this is really the best kernel I've ever tried, and belive me, I've tried them all.

Smothness, optimisation, Oc-uv and a lot of extra features that the other kernel makers didn't implement in their projects.

unused kernel modules in your SO kernel

hi

Let's say, it's your kernel, it's your nice work, you made it and i'm a proud and happy user of it, while observing another one's developements.

Now, one of it's particularities is the wide amount of filesystems supported...

Nice. but as no one is using ext3/XFS/BTRFS or ReiserFS for a fix at that time ( as far as i know ), should'nt it be a nice idea to publish a light, size optimized version for a bit more free memory ?

i've no idea of the size of those ( i think so ) unused .ko, but maybe they're eating a MB or more ?

Thanks anyway, and hope you're not offended by my thought.

Flash went fine, reboot fine, no apparent issues after a few minutes of use. Hard to tell any differences in so little time, so I'll play with it more in the morning.

I did run two quadrant scores after fresh boot with this kernel, got 973 and then 934, so no improvement on that front for me.

Just to be sure, the kernel I have in About on the phone is 2.6.32.9 root@sep-42 #1.

[Galaxy S I9000 Android Development] khutzang:
I'm on windows XP by the way. It's really basic. :) Just open the folder containing the kernel you downloaded. On the drop-down menu, click tools, folder options, then go to the "view" tab. Scroll down and look for "Hide extensions for known file types" and make sure it is unchecked. :)

This little fix will enable your pc to view the file extension (.zip for this case). The downloadable kernel here is named with a ".tar", but the very nature of the file was a ".zip", so all you have to do is follow the steps and then erase the ".zip". :) Cheers!

Holy poo this is fast. 2119 on Quadrant from around 1800.

Root works fine.

No recovery, but download works so when the OP fixes recovery and puts OC into this kernel ;) then it'll be OK to just flash again.

During the backing up and restoring process in ClockWorkMod Recovery , I'm aware of the backup image has been created in root/sdcard. My question is: Is the backup image deleted automatically after restoring with Voodoo? or else where might it be? because I want to delete it

(i don't wanna waste of phone memory space) :)

Well All ko are used and xfs was removed since 3_6 version(last one).
