Recently I've replaced a 7200 NPE-G1 router with so called better processor engine, NPE-G2. The router was handling something like 200-300mbps traffic on each 3 onboard interfaces, doing some inter VLAN routing, NAT, route-map and a small single area OSPF. The CPU usage at peak time was %70. We decided to replace it with a better NPE (NPE-G2) but surprisingly we didn't see any better performance from the new NPE-G2! The NPE-G1 didn't use even the MPF (Multi Processor Forwarding). As i checked the data sheets of both NPEs, it's clear that everything has been doubled from memory, PPS and even the CPU speed (700MHz to 1.67GHz!!!). I've seen some postings that even the onboard Gigabit ports cannot forward 400mbps as before (NPE-G1). Can any one explain what is going on with new CISCO products???
