Last comparison I read was in german c't magazine
(issue 2002/6 p.228) where they compared ext2, ext3, jfs,
reiserfs and xfs using (among others) postmark
Postmark is said to simulate a mailserver pretty well. Other
tests like tiobench revealed somewhat other results.

With postmark, xfs performed amazingly well, while jfs was even
slower than ext2/3 and reiser and had some reliablity problems.
But please note that things might have changed by now; versions
compared where ext3 0.9.16, jfs 1.0.15, reiserfs 3.6.25, xfs

Cheers, Marcel
