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 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
