The only optimization that comes to mind is Apache's processes
configuration.

However, does IMP+Postgres keep all the status info in Postgres, thus
multiple IMP servers would work?  Or does IMP depend upon Horde info
which is within a specific Apache server?

(I view multiple servers as a response time optimization, not as a
performance optimization, thus this isn't what was originally
requested...)
