Hi,
I was testing two servers yesterday and unless i misread something the more powerful one have very bad performance.
First one is i3 3GHz with 4G ram and 4 SATA disks in RAIDZ1 and running on FreeBSD 8.1
I run bonnie++ with
[CMD=""]bonnie++ -u root -d . -s 7876M -n 10:102400:1024:1024[/CMD]
and results are
Second one is dual quad Xeon 2.5GHz with 16G ram and 8 SATA disks in RAID10 connected to 3ware 9650SE and running on Freebsd 7.2
bonnie++ was run with
[CMD=""]bonnie++ -u root -d . -s 36372M -n 10:102400:1024:1024[/CMD]
and results are
write cache is enabled on 3ware
I upgraded firmware to the latest version
FreeBSD driver is
I think that HW raid10 with double amount of disks might give better result that SW raidz. I doubt that 8.1 is so much faster than 7.2
Is there anything I can test or optimize to make that 3ware faster.
regards
Uros
