We see resident memory (RSS) sizes of anywhere from 11-19MB for apache 
processes.  During "normal" load we have roughly 20 apache processes per 
server (3 servers).  Each server is a Dell 2650 with dual 2.4GHz cpus and 
1GB of RAM.  All Horde tables and sessions are stored on a separate MySQL 
server.

If your webmail server and mail server are fast enough to dispatch 
requests in a timely manner, you shouldn't have very many simultaneous 
apache processes running.
