[c-nsp] GSR ge-gbic-sc-b traffic limit?

One connection is to a 3550 (our upstream providor) the other is to a
6506, sup720, 8 port gbic blade
I rolled back to our 7500 with 2 geip+s,

We have been doing some synthetic testing on the 12000 today. 
2 servers, one eached connected to each interface, 
We are using iperf for benchmarking, it was giving us 300+mbit/sec with
~40000+ PPS 
Is there a better tool out there that would be better then iperf to see
if we get the same results as we did yesterday?

I'd be surprised to learn how a GSR card could jump to that kind of
latency without dropping massive amounts of packets.  What gear is
connecting to this GSR?

Anything OC12 or below MIGHT be Engine 0 (i.e. 6DS3, 12DS3, 4OC3, OC12).
Anything >OC12 <=OC48 MIGHT be Engine 1 (i.e. 8FE, old 4OC12, old OC48).
Anything <=OC48 is PROBABLY Engine 2 (i.e. 4OC12, OC48).

And as someone else mentioned, 'sh diag | i L3' is your friend here, at
least for cards you have in hand.
