[Dovecot] Dovecot stable slow

[Jeff Graves]

This might help:

3. Set dir_index features on hard disk.

# 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. 

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.
