Thanks for the write-up.  Were the underlying partitions aligned or did they
started at sector 63 like default?  Also, did you consider re-doing the
benchmark with ext4?  CentOS 5.5 includes ext4 (Red Hat Tech Preview) and I
wonder how it fares compared to JFS.

I recently set up a 6-disk RAID-6 on my new i5-750 backend.  I've not
benchmarked it, but I did use GPT partition tables on each disk with the
first partition starting at 2MB using gdisk (fdisk for GPT special utility).
