I used a Cisco 7200 VXR with NPE-400. I used two different 7200's with the exact same results. Bidirectional throughput on 1GbE is a fraction above 10%. Unidirectional is a bit better (23%). Singl line ACL drops it to 8% (permit ip any any). FE performance doesn't start to drop below line rate until you put more than two in the box. I have a powerpoint if you'd like it, but it is not meant to slander Cisco, just to convince my customers NOT to put GbE in a 7200! It is not a GbE platform!
I have personally seen a 7200 with PXF-chip and two PA-GE do NAT at 300megabit with a few (10-15) ftp streams going thru it. With more random load it wouldn't go much above 100 meg, though. And please, lab tests doesnt show it all. Does the Foundry have a route cache? How many entries? I have seen equipment that performs perfectly in the lab start to bog down when you put real traffic on them, because of route cache limitations (for instance, 256.000 entries starts to be problematic when you have thousands of customers running real internet traffic thru the device). -- Mikael Abrahamsson email: swmike@swm.pp.se
