    SubjectIDE performance drop between 2.4.23 and 2.6.0: fixed in 2.6.1
    -----BEGIN PGP SIGNED MESSAGE-----
    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!
