[c-nsp] High CPU util on a 2811 with two ipsec tunnels

[James Graebner [VPNtranet]]

I have a 2811 w/ AIM module terminating two 10m ipsec tunnels that is 
nearly always above 80% and often above 95% cpu util during the day.  
Buffers show no significant number of misses.  sh int switching shows 
that 100% of the outbound encrypted packets are being process switched.  
IOS C2800NM-ADVIPSERVICESK9-M), Version 12.4(15)T1.  Why would this 
traffic not be fast switched?
