I have already followed the cisco doc which mentions the 'high cpu usage caused by interrupts'. These steps did not lead to decrease my cpu usage. Can anybody point me in a direction to troubleshoot the traffic that is causing this high cpu usage? Could this problem be CEF related?
Still though, I am wondering what kind of hardware routers ISP's are using these days for the SOHO market. The standard router my ISP delivers on a 20mbit line, is a SMC 79xx router. I can't imagine these routers have better hardware built-in as Cisco does?
But, regarding this pdf, the cpu is indeed within expected ranges.
