[IDEA] Tweaks

Regarding point 4: mount options

defaults,noatime,nodiratime

Code:

root@xbian:/etc/default# hdparm -tT /dev/mmcblk0p2
/dev/mmcblk0p2:
Timing cached reads:   330 MB in  2.01 seconds = 164.55 MB/sec
Timing buffered disk reads:  52 MB in  3.09 seconds =  16.83 MB/sec

defaults

Code:

root@xbian:~# hdparm -tT /dev/mmcblk0p2
/dev/mmcblk0p2:
Timing cached reads:   324 MB in  2.00 seconds = 161.66 MB/sec
Timing buffered disk reads:  52 MB in  3.03 seconds =  17.14 MB/sec

So no big gain.

Regarding point6: NOOP scheduler

General:

http://en.wikipedia.org/wiki/Noop_scheduler

Bad result:
http://www.redhat.com/magazine/008jun05/features/schedulers/

Good result:
http://mynixworld.wordpress.com/2011/11/10/how-to-choose-the-right-kernel-io-scheduler/

So again, no clear result.
I will leave it for now, but perhaps will try Deadline later.
