Our server has the following caracteristics
PIII 1.13 ghz Dual processor
Imail average daily flow: 70,000 (4gb) messages in 20,000 (2gb)messages out
Top cpu consumers in consumption order. 1. Queue manager 2. SMTP 3. Webmessaging
Server only runs Imail, No external Anti-spam nor Anti-Virus.
That is very strange. The dual 1.13GHz processor should be able to handle at least double your current load without high CPU usage (with spam and virus scanning). So without spam or virus scanning, you shouldn't be seeing 90% CPU usage.
I'm not sure what in the Queue manager or SMTP could be causing such high CPU usage -- perhaps someone else on the list will come up with some suggestions of things to look for that may help determine why it is so high.
