[c-nsp] NPE-G1 throughput, with and without L2TP

[christian.macnevin at uk.bnpparibas.com]

Ooh, lookit that.

Hm, still only one CF reader - doesn't this annoy anyone else?

And why is it cisco's stuck with the separate fibre and copper interfaces 
instead of going with SFPs? I'm guessing they
just threw a bigger chip int othe same architecture, but it does seem odd 
to persist with that historical blip.

I'm surprised that no one has mentioned the G2 yet.  Just happened to
notice that earlier while looking for something else...

We get around 180Mbps (x2, coming from one interface and passing through
the 
other) spanning across ~3000 L2TP sessions before maxing (95%) the cpu.
But we 
use netflow+policing on most of these sessions, so we should get more if
we 
disable these.

PS: Still haven't tried MPF ;)
