I've been running bonnie++ filesystems testing on an IBM x335 server recently. This box uses the MPT RAID controller, but I've disabled the RAID and am addressing the disks individually. I'm getting wildly different results between 2.4.20-20-9 (RedHat mod), 2.4.22 (stock), and 2.6.0-test9.
The full results are here: http://groove.jpj.net/x335-test.html
The base distro is RedHat 9, there are no extraneous daemons running or modules loaded. I'm using a dedicated drive as the scratch directory. I'm looking for some insight as to why I'm seeing such a disparity in performance.
The server has Dual P4 3.06Ghz CPUs, 1.5GB RAM, two 36GB Ultra320 disks.
bonnie++ is run as
bonnie++ -d /test -s 3g -m x335-`uname -r` -n 200 -x 2 -u root -q
Thanks
-Paul
