Freebsd IP Forwarding performance (question, and some info) [7-stable, current, em, smp]

[Fabien Thomas]

For your information we have mesured 730Kpps using pollng and  
fastforwarding
with 64bits frame without loss (<0.001% packet loss) on a Spirent  
Smarbits (Pentium D 2.8GHZ + 8xGig em)

You can find the code / and some performance report at : http://www.netasq.com/opensource/pollng-rev1-freebsd.tgz

The best performance / CPU cost ratio is to use 1 core only and the  
others core are free to do application processing.
