The command:

router#show ip cef switching statistics feature

Will show you which feature is causing traffic to be punted to CPU.

You're on the right path.  The more important number is the packets in/out,
as opposed to the characters.  Look at the ratio of packets in/out for
processor vs. Route-cache for the two interfaces.  Fa0/1 is process
switching about 80% of them inbound.  That's pretty bad.    The output looks
better.  Compare that to VLAN 10, where in both directions, only about 10%
are process switched.  The stats for the switchports are meaningless, so you
can ignore those as the switch ASICs deal with those, until they hit the
VLAN int.  Figure out what feature (or IOS bug??) is causing so much process
switching, and I think it'll get better.
