[c-nsp] CE Router performance

I don't believe Cisco is claiming any such thing, they usually play it safe.

Cisco positions the 1900 series quote:
> "in high-speed WAN environments with concurrent services enabled
> up to 15 Mbps."

Now, you can push more than 100mbit/s through this box, no doubt,
but you are completely on your own. Routerperformance slide says
a 1941 pushes 299kpps or 150mbit/s (at 64byte packets), that gives
you a little room and you may reach 400mbit/s in lab conditions,
but you will be on your own (say a mandatory IOS upgrade due to
security bugfixes introduces a forwarding performance regression?).

This is really (quote) "never-to-exceed [...] feature-free CEF throughput".

Datasheet doesn't guarantee anything on ISR G1/G2. Get ISR 4k for
bandwidth guarantees.

Throughput means pushing traffic from one (ingress) interface to another
(egress) interface, so we are talking half duplex here.
