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).
