I have seen this in other instances as well. A 2811 never dips below 10%
(cpu is graphed) even off-peak with nothing going on. The 1700 it
replaced properly flat-lined to 0% at the same times.
It remains to be seen whether this is an aesthetic issue or an actual
problem.
I am looking at a G1 running 15.0 pushing a few hundred mbps peaking at
near 90% (cpu graph) without any user reported issues reaching me. Some
of that traffic is IOS FW, some is ATM, most is inter-vlan. Full tables.

Decided to move from IOS 12.4 to 15.0 (15.0(1)M7) on a 7206VXR with
NPE-G1. Since doing the upgrade, i've seen increased CPU usage in the
IP Input process. The configuration remained the same after the upgrade.
Verified CEF on all interfaces. Followed troubleshooting docs on Cisco's
site, as well as searching the archives of nsp. Not able to find any
info to help troubleshoot this issue. This is an edge router connecting
to our 2 upstream providers, taking full BGP routes. As of 4am (CST),
traffic is pretty much dead, less than 20Mbs going through, and CPU
usage is at 35%. Normally it's around 10% for this time of night. Any
ideas of what could be going on? I haven't downgraded the IOS just yet,
hoping to see if i might have missed something easy. Thanks,
