Some time back I did some benchmarks with "mailstone", and decided in the 
end to go with XFS on Linux. JFS was also fairly good. Now there is ext4; 
haven't tried that for mail, it's still somewhat experimental. I used it 
on Fedora 9 for a while but things crashed (possibly unrelated) and the 
absence of ext4 support in the rescue disk killed me. It did seem 
significantly faster than ext3.

Since then, we tried using XFS on iSCSI which was a disaster, at least 
under RHEL 4.
