High CPU utilization w/VRF NAT - Cat6500

~80 or so static NAT's configured, multiple versions of IOS tested. Most of the traffic is being punted to the CPU through the NAT interfaces causing high CPU utilization. Increasing fast aging timers had 0 benefit, TCAM utilization is less than 5% Does anyone have any thoughts on other configuration tweaks I should try? I think we're at the point where new hardware maybe FWSM or another platform for NAT should be explored. --RB
