I'd say very good, if compared to my results :-)

This is what I get:

thinkpad:/usr/local/doc/muttng# hdparm -Tt /dev/hda

/dev/hda:
 Timing cached reads:   1628 MB in  2.00 seconds = 812.40 MB/sec
 Timing buffered disk reads:   80 MB in  3.05 seconds =  26.25 MB/sec

I get this result repeatedly, there is no other disc I/O during the
test.

thinkpad:/usr/local/doc/muttng# hdparm -i /dev/hda

/dev/hda:

thinkpad:/usr/local/doc/muttng# hdparm /dev/hda

/dev/hda:
 multcount    =  0 (off)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)

 readahead    = 256 (on)
 geometry     = 65535/16/63, sectors = 78140160, start = 0

This is a rather old R40 (about 2 1/2 years) running Debian Sid with
kernel 2.6.17-rc3, so I guess I'll just have to live with these results?

Wolf
