The problem was particularly pronounced on the 75xx/85xx series cards (which were not exactly RAID5 speed demons). XFS blew away ext3 on hardware RAID5 arrays on those cards. I don't have any benchmarks handy on 95xx series cards, bit I vaguely recall that XFS still performed better, but not by anywhere near the same margin. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
