Dear all, One of our mail server (cluster member) is slow responding during 8:00-9:00 am. But this can be solved by shut down the router task.
But I can’t shut down the router for a hour.
I found that the AI is always below 15 during that period.
Any idea ??
Thank you very much !!

Subject: RE: Server slow responding caused by router
These types of issues are hard to troubleshoot. Is your router actually routing mail from 8-9? If so, what is generating all that mail? It could be users, agents, rules, etc. Is the server overloaded with users and they all arrive to work between 8 and 9 and start using mail heavily?Besides all that, we have found misconfigured anti-virus programs, backup programs, program documents, scheduled operating system tasks, replication (and more) can contribute to performance issues. You are lucky it happens at a certain time every day so you can troubleshoot it.
Sorry I don’t have a better answer, but performance issues are tough.
