RE: [nsp] 2 T1 handling router

It depends on what your doing on the router. If your doing NAT, that adds
more load, plus forces the packets to be process switched. That's a serious
performance hit. A 2500 doing NAT on 2 T1s will choke at full load. If it
can fast switch all the packets, it'll handle two full T's. Compression and
ACLs also add to the problem.

If you are, then something else is wrong.
