Root Comparison of IO Schedulers

[cubmoney]

Well, since I couldn't find anything pertaining to the Motorola Triumph as to what is the best IO scheduler, I decided to undertake some tests using Androbench (found on market). Tests were performed on CM7, using bkernel overclocked to 1.5GHz using smartassv2 governor.

MBSR=MB/s Sequential Read
MBSW=MB/s Sequential Write
RRIOPS=Random Reads IO's/s
RWIOPS=Random Writes IO's/s

RESULT:
Noop is overall the best in my opinion.

Yeah no-op is a very good scheduler because it doesn't schedule at all. That's why it works well on band where you don't have to worry about spinning disks up and moving the arm and everything. No-op sucks on hard disks lol!

I don't know much or anything at all about IO schedulers but I noticed a nice performance increase after enabling the tweak cfq IO scheduler option in Auto-Killer. Said something about fixing the spinning disk thing.

Yeah, I have my tweak script in my ROMs mark every partition as non-rotational. It helps out somewhat. They are all good schedulers though!
