File system is also very important!
The default EXT3 format is no good.
You should tweak EXT3 to use dir_index
dir_index is a hashed b-tree implementation for ext3,
to update an existing partitions as root:
unmount your file system.
1) tune2fs -O dir_index /dev/sdXY
2) e2fsck -D /dev/hdXY
mount it back on
Or I do tune2fs -O dir_index /dev/sdXY at partition creation.
My personal preference though is JFS for really big partitions.
Because JFS performs fast and at fsck is super fast.
Go go go.

Convert your qmailtoaster from Courier IMAP to Dovecot IMAP.
Dovecot is fast!
And the speed difference will become more apparent as mailbox sizes
grow. What is the minimum and maximum Maildir size for your users?
Having said this, it's probably a good idea to also check if the
bottleneck is somewhere outside of QMT. Eg: Your network or disk(s).
