Here is the rawio stats for a 3.4-STABLE box running a Dell PERC2/SC card
(I think it's an OEM AMI MegaRAID Express 300).
Random read Sequential read Random write Sequential write
ID K/sec /sec K/sec /sec K/sec /sec K/sec /sec
PERC2/SC 5533.6 344 19268.6 1176 881.6 54 1034.6 63
This is on a Dell PowerEdge 4300, pIII/450 connected via a single bus to 8
x 18Gb LVD disks (1 x hot spare, the rest in 1 array).
This is using the amr-stable patch produced by Mike in December last year,
with the lockup fix backported from 4.0-STABLE (heh, 2 lines, wasn't
hard).
We're about to throw this into production.
Carl.
