are noticing a fairly high CPU load compared what we were used to on the older 3550's.
It looks like we are punting packets like crazy...

I think crazy punting would go into the "sw forwarding" line (and deliver high latency to your customers), but you appear to have a big "icmp" line. Maybe you are just generating a lot of ICMP unreachables for the usual reasons, and maybe this is more difficult for a 3400 than it is for a 3550.
I would try to "deb plat cpu-queues software-fwd-q" (this is guaranteed to be a heavy debug for your CPU) to see what kind of packets the CPU is transmitting/receiving.
I know this is not much but hope this helps somehow. Bergonz -- Ing. Michele Bergonzoni - Laboratori Guglielmo Marconi S.p.a.
