I think that Robert Olssons post never made it through the filters...

400 kpps is decent but it all depends on your setup what you''re
testing.
Single flow?
Number of packets in environment with hi-number of flows. ( Forces
lookup of dst cache, route lookup and garbage collection) is the most
challenging Also how to handle filters eventually stateful information.
For single flow tests most things end up in L2-cache and we most
limited to latency. Bus latency, Memory latency etc.
Large packets bus and memory bandwidth.
We''ve seen 500 kpps in some of our production routers for BGP and
about 500 filters. Dual Opteron 2.6 GHz. But you need to have a
"setup"
routing so it can make best use of your HW.
