We have two domino servers hosting about 100 users each. We use it strictly for mail and do not host any applications. We are running two 3.0Ghz quad processors with 4GB Ram each. However, we are seeing very poor performance mainly due to high IO activity - we do receive quite a bit of email (the avg db size is 1GB). The servers do not run anything else but Domino, and the event logs do not show any relevant errors. There does not appear to be any Domino tasks running amok. I would like to draw on the wealth of experience in EE land and ask:
1) How many users do each of you host on each server?
2) Are there any monitoring tools outside of Domino that can assist?
3) Where would I find some good references for improving performance?
