I'm not a 'filesystem' guy, but is my assumption correct that XFS is 
great for large files and reiserfs is good for a ton of tiny files?

On my mail server, I used reiserfs.  Is there a better (faster) 
filesystem choice here?  And on my MythTV box at home, I used XFS 
because the only thing on the partition is large video files.
