Does anyone know the differences/benefits/etc. of each CPU Scheduler? Noop, CFQ, and Deadline?
Thank you in advance!

Noop Imo is the best for flash memory and or ssd, deadline a close second... Then cfq/bfq which would be number 1 on a desktop pc..

Try using smartass V2.. It offers the best of both the world!
I use Scary governer for saving battery. It is basicly modified conservative.
Ok for gaming I will use performance

Battery saving scary
What about scheduler?
SIO ofcourse is the best IO sheduler out there....

[Q] Stock Governor and IO Scheduler

I have changed kernels, governors, and io schedulers so many times that I no longer remember what the stock settings are. Can someone who hasn't changed kernels nor modified these tell me what the stock settings are?
Thanks.
I believe it's ondemand and cfq (maybe noop)

what governor do you use?

i don't game at all, i just want the device to be snappy with my constant switching between facebook, viber, whatsapp...etc
which governor should i use? and should be the min, max CPU speed? i can go up to 1804Mhz but i prefer not to overclock if possible

I personally recommend SIO governor, it's good enough for me or maybe if you're on CM10.1 you could try the FIOPS or BFS governor to from Hurtsky 3.4.xx version one. Cause it could even handle switching from whatsapp and light games to.
Could try which one suit you better..
