Running on a Cisco 7507 [RSP4, ip cef], with IOS 12.0(11). CPU was at
15%. After turning on tcp intercept CPU runs around 40-50%. Typical level
of SYNs runs around:

dexamol#sho tcp inter stat
Intercepting new connections using access-list 120
34 incomplete, 292 established connections (total 326)
367 connection requests per minute

Does anyone know how to reduce CPU when running tcp intercept?
