Wow - that's interesting. I didn't know there was a btree option for 
Ext3. I thought only Reiser had that. If this actually works then it 
should perform like Reiser.

Not trying to get into a religious war about file systems but when you 
are looking at 100,000 files in a single directory you need a database 
type index to get any performance. That's why I'm a reiser fan for this 
purpose. If Ext3 has that then that's exciting. Of course you have to do 
whatever it takes to make that work because Ext3 didn't used to be that 
way.

Does XFS have a btree search in it?
