Here are my speed optimized kernels for samsung touchwiz jellybean, cm11 and aokp kitkat based roms
(many thx to Hank87 http://forum.xda-developers.com/member.php?u=4595544 for testing the many samsung touchwiz test kernels)

V1.2.1:
auto root (tw kernel)
cwm added (tw kernel)

fixed an bug that could make connecting to network very slow
rwsem: steal writing sem for better performance
ondemand: enabled counting iowait as busy for exynos too
kernel fixes for linaro gcc
kernel with AIO enabled
AIO: Don't plug the I/O queue in do_io_submit()
ROW as default io scheduler
build with linaro gcc 4.9.2
kernel build with -Ofast
faux123`s dyn fsync
optimized arm rwsem algorithmfixed an bug that could make the oc kernel unstable
overclock version with 1600mhz max with 16 step frequency table and reduced core voltage
overclock version with 1500mhz max with 15 step frequency table and optimized core voltage
standard version with 1400mhz max with 14 step frequency table and optimized core voltage
on idle cpu can go to 100mhz instead of 200mhz for longer battery life
higher (but save) thermal throttling values
optimized vm values
multithread dexopt enabled

57hz - 59hz is completely safe. If you go beyond that, bootanimation will start to derp (turn off/on the screen once it's fully booted and you're good to go). Also you will have no access to the recovery. I only experienced that on AOSP, though. On Touchwiz I could go to 62hz without a problem. 64hz is fine with the workaround above.

It improves smoothness and lowers latency by quite a good margin (~17ms at 57hz, ~16ms at 60hz, ~15ms at 64hz).

Also, good luck with your kernel!

Hello Bauner

First of all thank u very much for a great kernel. I have tested the non OC and OC 1.5. Everything runs smoothly except for stock video player that got busted with the OC'ed vers just like forest's. I have yet to test battery as I have just completed one battery cycle. Will update if there's anything pops.

I also test it for 2 days on DU Rom and it is working smooth. I'm using the non OC version but it seems the kernel loves to stick on 1.1 and 1.4 speed which is why the battery drains much faster.

I also noticed that when Wifi is on and while screen off, it seems to drain also much faster, while on stock it consumes about 150-170mah on this kernel it consumes 230-250mah.

What I'm happy about this kernel though is that it seems to resolve my issue with Dynamic Colors on DU as I had no single reboots while using it. On stock kernel I had reboots when using Dynamic Colors.

Is there a way that instead of always using 1100 speed, it will use a lower frequency like 800 or 900?

Many thanks for the kernel!
