It is based on known load for that number of tunnels. We have NetScreen
100 firewalls and NetScreen 500 firewalls in production. The model 100's
tend to hover around 60% CPU with active 120 active tunnels. The model
500's are running 40-50% CPU with ~200 active tunnels. Bandwidth
utilization is about 10Mbps of AES128 traffic.

Fair enough.
