Researching, I found that there are tools such as LoadSim and JetStress that are to be used before a rollout. The Microsoft Troubleshooting Exchange Performance White papers goes over RPC request and operations, but does not give an example to or refer to low RPC request/High RPC operations. Disk performance seem to be fine. No redlights here: Disk Reads/sec = below 50 (total) even lower per cpu. Disk writes are a little higher but not bad. Avg. Disk queue Lenght is very low. Does this help? http://www.MSExchange.org/ Have you seen the troubleshooting docs on http://www.microsoft.com/exchange/library site? Also, have you looked at disk utilization? What did you see?

I am using spotlight for exchange to monitor. Emails appears to be flowing fine. I just keep getting errors from spotlight the MSExchangeIS\RPC operations per sec are dramatically high for each server. The warning threshold is set to 5 and I am seeing numbers in the sixties and seventies. I have been looking for articles that maybe able to tell me the cause of this, but I am not having much luck. All the servers have 4GM RAM with the 3/GB switch and four processors. My single server is using a single gigabit ethernet adapter. My cluster of course is using a private Gigabit and a public gigbit adapter. Exchange 2000 Advanced server. My cluster has 1205 mailboxes and says it has 4106 MAPI connections. My single server has 809 mailboxes and claiming 2426 MAPI connections. Any Ideas?
