Why are you concerned with this load? You're seeing an average load of
up to 30% on your per-minute stats, which is not really high, is it? The
spikes you see (the max cpu) is likely from the BGP scanner, which is
doing its job scanning the full Internet table. Nothing wrong with this,
it's a low priority process, so if something more urgent comes along, it
will just sleep..

Based on the data you've just posted: I would investigate why
GigabitEthernet0/1 shows such a high number if process-switched packets,
but as long as you don't spend much CPU time in the IP Input process
(which you don't, according to the "show proc cpu" you've posted), I
wouldn't worry about it. Clear the counters and keep an eye on it..
