The performance drop is rather high with the any kind of tunnel regardless
of their number: the delay increases 50-100% percent than native
connection, depending on the load of the box and links. The decapsulation
is the most CPU intensive for Cisco 7200.
The handled number of tunnels is mostly depending only on the amount of
memory you have. If you have low amount of traffic, then you can easily
terminate 1000s of tunnels...
