[c-nsp] 3845 maxing out at 400 Mbps

[Frank Bulk]

Let me clear the air and say that I'm very happy with the performance of our
3845s -- they've done much better than even our consulting company thought
they would.  

They need to last just a few more weeks until the new border routers we
ordered come in and we turn them up.  I just need to buy a few more weeks'
time.  

What prompted the initial question was that I was seeing different behavior
between the two (identical) routers.  That gave me a unique opportunity to
compare and contrast.  I think the HWIC is likely the culprit here.

I believe the marketing blurb for the 3845 was "full T3 with
concurrent services."  Even this is a stretch of reality.  A
voice-heavy traffic mix (avg 300 bytes/packet) while using GRE/IPSec
brings the 3845, and it's younger sibling the 3945, to it's knees
around 35-40Mb/s.
