I don't know how many people have seen this but it may be of interest or useful.
Benchmarking Filesystems <http://linuxgazette.net/102/piszcz.html>
This article covers ext2, ext3, JFS, REISERFS and XFS.
I found it interesting.
I found it useless.
Test done on a vanilla 2.4.26
A far more interesting one can be found at http://untroubled.org/benchmarking/2004-04/
which simulates real world conditions for mta boxes with recent kernels and not with a kernel that is not going to receive much attention anymore.
Add to that that things have changed so much in 2.6 from 2.4 that fs code is substantially different. eg: XFS in 2.4 is different from XFS in 2.6
Now Bruce Guenter's benchmark is a much more well thought out model of a benchmark and performed on all options available.
