[j-nsp] EX Routing Throughput

[Paul Stewart]

I seen similar results at a customer site with testing - I asked the person
who was looking into this ... response I got was "that's about right for a
switch running at line rate"... never took any time to understand his
response.  Does this make sense to anyone else?  My understanding of "line
rate" was simply that a 10GE port could do 10GE (or VERY close to it).
Thankfully that particular site does about 3.5Gb/s so no major issue...

Maybe a bit late, but this is the most I saw on an EX4200 on 10GE
ports under test.

 The PFE and the CPU were not showing any usage, maybe 1% or so.
