I saw a definite improvement by turning off NCQ and setting StorSave
to 'Balanced.' Are these 1.5GB/Sec or 3.0GB/Sec SATA drives? During my
testing I changed from non-interleaved memory and 1.5GB to interleaved
and 3.0GB. Made a big difference in bonnie++ results. Unfortunately, I
can't say which was more important.
If you have the patience, read through my recent (but lengthy) thread
on the 3Ware 9550 titled "Calling All FS Fanatics." There's a lot of
good info from many helpful people. I've only gotten full performance
using JFS or XFS.
I'm doing this from memory as the machine is at another location now. I
think I did this:
turned off ncq (per Josh's suggestion)
turned on write caching (it's on an oversized ups and the data isn't
critical)
set storsave to "performance"
changed the memory interleave (thanks to kirk's suggestion). It was off
by default.
used parted to create gpt disklabel
set noatime and one other option that was suggested here for the RAID
partition
used mke2fs -j -b 4096 /dev/blah
That was it.
Also, I tried the same array as a RAID0 device on the same box and the
performance was approximately the same (maybe ever so slightly faster).
Cheers,
