I'm interested in your experience with this.
Do you have any kind of statistics? How big is your mailbox, 
how many messages in it, and how long did it take to display them?

I know its all a bit subjective, but we have recently had
issues about mail-response and switching to cyrus-imap
was discussed. However, when I looked in more detail
at what was going on, I found many of our 700 users with
all their mail in the mail spool, others with Gigabyte inboxes
on their home disks and suchlike. When we addressed these
issues, mail response improved dramatically, even with the
compatible-but-horribly-slow mbox format (which we maintain
partly because of inertiia and partly because many users
want to read their mail with different mailers depending
where they are)

Cheers,
Terry.
