[c-nsp] Your opinions on router throughput

Hi All,

  It's OK guys, I asked a somewhat open-ended question because I wanted
the discussion.

  I already know what both VXR's with the NPE300's are doing in their
existing
circumstances - show proc gives me that.  Right now they are running at 10%
CPU utilization with cef turned on and 2 BGP views.  It is useful to know
that
others are seeing the same utiliztion in "normal" circumstances.

  It is also almost even more useful to know how the devices will react in
"abnormal" circumstances. :-)

Ted
