If you do put on FreeBSD 6, I'd love to see the output of "diskinfo

i have a HP dl380 g3 with array 5i controlled (1+0), these are my
results
[...]
is this good enough?
Is that on a loaded box or a mostly quiet box? Those number seem
rather low for my tastes. For comparison, here are numbers from a
Dell 1850 with a built-in PERC 4e/Si RAID in a two disk mirror. All
numbers below are on mostly or totally quiet disk systems.
My numbers are on totally quiet box, i've just installed it.

Seek times:
Full stroke: 250 iter in 0.756718 sec = 3.027 msec
Half stroke: 250 iter in 0.717824 sec = 2.871 msec
Quarter stroke: 500 iter in 1.972368 sec = 3.945 msec
Short forward: 400 iter in 1.193179 sec = 2.983 msec
Short backward: 400 iter in 1.322440 sec = 3.306 msec
Seq outer: 2048 iter in 0.271402 sec = 0.133 msec
Seq inner: 2048 iter in 0.271151 sec = 0.132 msec
Transfer rates:
outside: 102400 kbytes in 1.080339 sec = 94785
kbytes/sec
middle: 102400 kbytes in 1.166021 sec = 87820
kbytes/sec
inside: 102400 kbytes in 1.461498 sec = 70065
kbytes/sec
Umm, in my box i see better seektimes but worst transfer rates, does it
make sense?
i think i have something wrong, the question i cant answer is what
tunning am i missing?
