hi!
sorry for the delay in giving you feedback on the performance of the
modified murder setup.
we activated the new setup ( 2x murder backend, 2x murder frontend, 4x
smtp ) by the end of last week.
with the smtp load gone, the murder frontends perform very well. load
varies between 0.5 and 1.5,

we use compaq dl360g3 on all machines. they are equipped with 2x Intel
Xeon 2.8GHz and 2GB RAM. 4 70GB hdds are configured

I've seen this enough on our systems that I use sasldb

We are in the process of converting UW Imap to Cyrus Imap. We have about
10K users using about 100K mailboxes. We anticipate the number of users
to increase to 15K.

Cyrus Configuration for murder hardware. What is not clear to me
