Have you searched through this mailing list? There have been a few past
discussions on this, including my own experience:-

My setup above also includes VISP, directory entries are straight forward,
only issue is arranging the mailbox storage on your disk subsystem for
performance. (More a mailbox I/O issue, not an LDAP/MySQL issue).

So far I have no performance issues with OpenLDAP in my setup above. I
don't have MySQL as same role as comparison, so I can't comment on MySQL
Usually (in simple email services) you would probably hit disk I/O loads
first before LDAP/SQL.. but still depends on your particular system.
