Performance root cause

hi Team,

We have XI 7.0 running and 6 hours back we had experienced slowness in message processing.

But over period of time, the overall performance back to normal. So now i need analysis why there was slowness in message processing. Please help me with some quick tips to find the reasons for the same.

We have Wily Introscope, SMD, in our environment.

Thanks

Sekhar
