Sometimes I have the feeling that we are the only one which are using
cobalts in business.

The Problem is a 450MHZ CPU with 5400rpm ide harddisc and a _really_ high
visited / used domain (approx 6-9 mailrequests/sec - depends on daytime)

What I ve seen until now a RaQ4 can only handle 300 - 500 users _without_
running into troubles. Above that you have to reconfigure services to accept
high load (ie "MTA refuses connection due to high load", or the standard 40
connections per service per minute, and so on...)
