i was trying to find out the same thing a few weeks back..

from what I understand, the 2.6 kernel has some significant 
optimisations to ext3... i think ext3 may now have B-trees to speed up 
access to directories with a lot of files/subdirectories? can anyone 
confirm this?

I was also looking at Reiser as an alternative... but as RH doesn't 
support it at all anymore,  i didn't want to risk my precious maildirs  :)
