You might want to look at: http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a00800a70f2.shtml

Also, if you can post your show proc cpu when its very high, other suggestions might be provided.


Do note, that routers have a finite capacity, so sometimes the traffic load require a more powerful box.

From the show cpu process listing you provided, looks like your cpu hits are bursty and I don't see any software process with a look term high utilization.
