Hash: SHA1
Using hdparm -Tt /dev/hdb:
on 2.4:
~ Timing buffer-cache reads: 168 MB in 2.01 seconds = 83.58 MB/sec
~ Timing buffered disk reads: 44 MB in 3.12 seconds = 14.10 MB/sec
on 2.6.0:
~ Timing buffer-cache reads: 172 MB in 2.02 seconds = 84.95 MB/sec
~ Timing buffered disk reads: 34 MB in 3.08 seconds = 11.04 MB/sec
on 2.6.1:
~ Timing buffer-cache reads: 172 MB in 2.01 seconds = 85.14 MB/sec
~ Timing buffered disk reads: 44 MB in 3.07 seconds = 14.35 MB/sec
and that straight after boot, without any tweaking from hdparm.
Great job: many thanks!
