mbox is more efficient than maildir for many common operations,
specifically from a filesystem IO perspective:

1.  new mail delivery
2.  searching a mailbox folder
3.  mass deletion of emails from one mailbox folder

maildir is more IO efficient when reading and deleting individual emails.

mbox puts the load on the mail server application and on memory.
maildir puts the load on the IO subsysetem.  Which is precisely why Timo
created the mdbox mail storage format, attempting to get the best of
both worlds.
