I was going to bring up something like that, but I wasn't sure it was 
fair comparing my server.

I do not have SSD's. But, I have a larger user base and I have a Sun 
T5220, which is 8 core, 8 threads per core, etc. The drives are 15Krpm 
SAS. Using Sendmail, mimedefang, Dovecot, Squirrelmail, etc. Also 
running Apache2 with Drupal, MySQL, gene sequencing apps, PostgreSQL, 
Samba for file sharing and printer spooling, as well as some other 
stuff. Squirrelmail/Dovecot is virtually instantaneous even with very 
large mbox format inboxes. Thunderbird mail checks via Dovecot are also 
virtually instantaneous. I have over 1500 accounts on the system, 
although probably only a few hundred are very active. Granted, it is 
summer, and things will pick up in the Fall, but I doubt it will push 
this server too much.
