See what this looks like now I have configured Zarafa fully...
(For interest sake, I'm running our double NIC interface mailserver/gateway on an 800Mhz VIA CPU. With three users performance is fine - I needed to turn off one of the indexers).
model name : VIA Esther processor 1000MHz
stepping : 9
cpu MHz : 800.000
cache size : 128 KB
To up the number of services I can comfortably run I will upgrade to 1.5Mhz.
