[c-nsp] Real life performance of NPE G1/G2?

[Garry]

Hi,

I was wondering, what real life performance can one expect from an NPE
G1, considering mostly vanilla IP routing/forwarding? (no ACLs, no VPNs,
running CEF and MPLS VRFs, OSPF/iBGP for routing protocol, and utilizing
the integrated Gbit interfaces as well as 1-2 STM1 PAs on the 7200 VXR
chassis)
I know the performance charts from Cisco talk about 1 MPPS for the G1,
which equals to ~640 Mbit throughput  @ 64 bytes per packet - to what
extent is that "worst case"? I know on the NPE300/400 cards, the "worst
case" throughput pretty much is the real life throughput - does the G1
perform better by using HW forwarding? I would like to see some real
throughput in the 1Gbit/s range, assuming that flows that could fill it
up rarely use 64bytes per packet, but 1k and upward ...

Thanks, -gg
