What could cause a high percentage of packets being processed switched on a 7206-VXR NPE-400 router? This is our internet router with a DS3 link to our provider. We do receive the entire BGP table, but I think we have enough memory to accommodate that.
Here is a portion of 'sh ver' and 'sh bgp ipv4 un summary':

I've also attached a portion of the config and the output of 'show interfaces switching.
Any idea what may be causing such a high percentage of process switched packets?
