Hello
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..

No I mean tell two differently one for gaming n other for saving battery
? Still searching for answer
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
N normal smartass
Battery saving scary
What about scheduler?
SIO ofcourse is the best IO sheduler out there....
I use SIO too.

why not?
works fine, stock on android...
changing it caused unstability for me, or apps that never get closed by the system, just run on background, wich I dont want
My gio:
min 320 MHz
max 940 MHz
governor ondemand
rom giospeedo v2 + own mods
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)

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..
