10-15MBps ... then add a few hundred concurrent pop & imap sessions plus
some monitoring/statistical script walking your spool doing various
operations and see this number fall down dramatically ... Because with
random i/o ops you increase time disk heads travel around and add latency to
the whole setup.

The only thing that helps here is having lots and lots of disks or hw raid
controllers with nice big caches. Just what 'lots' and 'big' means depends
much on your actual needs.
