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.)
-----------
Depends if you are using standard route caching or Cisco Express Forwarding.
The 7500s should support dCEF if memory strikes me correctly. In any case,
when CEF is available it should be used. Comparing any Cisco router w/o CEF or
MLS wouldn't exactly be a fair comparison. MLS will care about new flows but
CEF will not.

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