While reading one of the pages posted on the list, I came across this:

�Total CPU utilization shouldn't be used as a measure of the ability
of the router to switch more packets. On Cisco 7500 routers, Versatile
Interface Processors (VIP) and Route/Switch Processors (RSP) don't
report linear CPU utilization. Close to half of the switching
packet-per-second power comes after 90 - 95 percent CPU utilization.

Can anyone explain what does the above mean? Does it mean that a 7500
can perform well even after a cpu load of 95%?
