Our 4506 is our core switch as well as the bridge in our network. Every port is connected and utilized. This branch is an R&D center so it's pretty busy. When I do a "sh cpu proc hist" I get:

As you can see the average only jumps to 40% but the max is up there quite frequently. We have been noticing some network slowness from time to time but we're not sure if the switch or not since port forwarding occurs in hardware.
Is it normal for a heavy utilized switch to spike up to 100% that frequently?
