We have two 3845's as border routers, each with three GigE interfaces (one facing upstream, the other downstream, the third facing the other 3845). The first 3845 has a typical packet-size mix (residential/business Internet) is consistently maxing out at 400 Mbps (predominately ingress because of asymmetric routing) running at about 43 kpps and 40% CPU. It's flat-lines very evenly, uncannily so. We checked and double-checked transport and it's set much higher, the same as the second 3845.
The second 3845, which has a mix of both ingress and egress traffic at a combined 82 kpps (35 kpps ingress/50 kpps egress) but lower combined 360 Mbps operates at a higher CPU (presumably because there's also egress traffic) with no flatlining. The ACLs are BCP 38-oriented with eBGP; no rate-limiting. We're running 124-11.XW2. Any ideas? The numbers are well below Cisco's router spec sheet.
