We have almost 30.000 active users and our life was sad with Maildir & backup: 24 hours for a full backup  with bacula (zlib enabled maildirs, 1.4 TB). After switching to mdbox, the backup time is under 12 hours ! Instead of backing 17 millions files, with mdbox our backup is only of 1 million files, and that speeds up a lot the backup operation.

Hmm. I guess if you were doing backups 24h/day, then you can't really say how much faster mdbox performs than maildir (outside backups)?
