ok - thanks.

ah - ok. I understand the results now. Basically it sounds like
default bonnie++ behaviour is being unrealistically nice to
ext2/ReiserFS and unrealistically cruel to XFS :-)
Perhaps a bonnie++ run with small but non-zero size files would be more
realistic, and might force ReiserFS to do more work. I'll give that a go.
Can I ask what the state of software RAID0 and RAID5 is? I note from
the list archives that there has been some success, but it's not
clear how stable things are.
