This might help:

tune2fs -l /dev/hda3 | grep features
if you see dir_index then you are all set. If dir_index is missing then add it using: # umount /dev/hda3 # tune2fs -O dir_index /dev/hda3 # e2fsck -fD /dev/hda3 # mount /dev/hda3 Now you can handle ginormous maildir directories with out breaking a sweat.
Actually, we're using reiserfs for all our server filesystems, which everything I've read about it says it's generally a much better performer for maildir than ext3 in most respects.
When we switched from UW-IMAP mbox to dovecot maildir it was slightly slower (3% maybe) at downloading headers but much faster in every other aspect.

A few days ago I installed dovecot stable to replace uw-imap. The install went well and all boxes were converted ok. When accessing the new imap server though, certain operations seem much slower, in particular, moving mail between boxes is very slow, and I have received several complaints from users that the mail server has slowed down. I can't figure out what the slow point is as maildir should be faster than mbox.
I sense much NT in you. NT leads to Bluescreen. Bluescreen leads to downtime. Downtime leads to suffering. NT is the path to the darkside. Powerful Unix is.
