I doing some performance test with openbsd 3.8 in a PowerEdge 830 with
perc 4/sc board.
'dd if=/dev/sd0c of=/home/test1 count=4000 bs=256k' gives a transfer
rate of 6MByte por second. This is really slow... other operating
systems get a throughput of 45 mbyte por second.
Setting Write-policy to Write Back in BIOS i doesn't help. The board
parameters are:
write policy: write back
read policy: adaptative
cache policy: cached i/o
dmesg:
