We have an Active Passive cluster with 1000 users on that is running at 80%-90% of % Processor Time. It has dual 2Ghz Xeons and 3Gb of Memory and is runnnig on 2K3 Server. Disk Space is not a massive issue with 30GB free on all drives.
We have a similar spec box with 300 users that is running at less than 5% which feels a lot better.
Has anyone got any ideas if this is a normal thing or if we have anything else that could do with looking at? or are we looking at replacing/adding some processors?
