RE: [nsp] [nsp] performance of an IO-GE+E vs PA-GE

Hello,

  I agree with you: it's not a tipical real word app: 8000 user @
100Mbps
yields around 13kbps/user. So basically it's a demontration of the
capability
to terminate the 8000 users, it's not the demonstration of the
performance.

  on the 50kpps: I'm just curious, which ios are you running?

Thanks,
 --Zoltan

Hmm, I find it hard to believe that will work in a real world situation.
Our experience shows that an NPE-300 runs out of CPU at about 50,000pps
(Cisco claim 300,000pps) doing normal IP routing, and about 1500 L2TP
terminations.
