I noticed a significant performance improvement when moving from ext3 to 
reiserfs, and consider it well worth it. That said, reiserfs doesn't 
play especially well with LVM snapshots, so there's a significant 
downside. Some people swear by XFS - and it /does/ work brilliantly with 
LVM - but there have been reports of unreliability and FS corruption.
