Hi Guys
I am having trouble with high CPU load on a 7500 cards. It would seem that most of the traffic is being processed switched and I am not getting close to the designed thruput of the card. The interface is a GEIP+, but the other cards in the router seem quite busy too.
I am running quite an old IOS version, so I am going to investigate upgrading, but I can’t see any bugs in the bugtool kit which would cause this? Can anyone see anything that I have missed or being stupid about?

As you can see most of the IP Process is being switched ☹
