Indeed.

Cisco 7500 with proper configuration would do quite well in this test,
too, even with ACLs.  Only if you have more than a few thousand new
flows per second, things start to look rather bleak.  (Forwarding
decisions are performed once per flow on this platform.)

I'd also like to see tests with random source/destination
combinations, just to keep things in perspective. 8-)
