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.
