That might explain why bonnie++ results were quite similar on IDE as on
SCSI. I just ran rawio on the plain IDE disk, and the RAID10 vinum
volume, and now results *ARE* 'astonishing' :)
Random read Sequential read Random write Sequential write
ID K/sec /sec K/sec /sec K/sec /sec K/sec /sec
IDE 1860.4 72 6799.4 415 1314.9 158 5914.3 361
VINUM 12008.3 724 14972.7 914 12072.5 726 13710.0 837
Thanks for all your help Greg!
Sander.
