- Maildir performance depends on the _number_ of messages
- Mbox performance depends ont the _size_ of the mailbox
- Maildir is better for concurrent mailbox access or mail storage on
"bad locks handling fs" like nfs.

What is maildir format and why:

All those preceding items makes me prefers maildir and particularly
postfix+maildrop+courier-imap than other free softwares.
My 3,14 cents ;-)
