[c-nsp] NPE-G1 / G2 performance

[Lee]

We had a solution involving NAT on some 6500s - it didn't take long
for them to run out of memory & reboot.  Cisco eventually said there
was a limitation of ~57K NAT translations on the PFC3B.   We added a
ip nat translation max-entries 50000
to the configs and asked our security office to pretty please NOT do
any more Nessus scans <there>.  That fixed the rebooting issue, but I
think we're back to not doing NAT on any 6500s now.

Regards,
Lee
