xfs and reiserfs are _huge_ wins over ext3 for news servers.
1) Did you try this on 2.4 or 2.6? 2.6 ext3 (with htree and
reservations) is like a 3x improvement over the 2.4 ext3 in many
workloads and is sometimes even slightly better than reiserfs in the
"milions of files in a directory" scenario.
2) Did you set the ext3 journalling mode to be on par with reiserfs/xfs?
(By default ext3 uses a more strict journalling mode to increase data
integrity but that costs some performance vs reiserfs and xfs that don't
have this extra protection)
