Here are my own benchs using smallest packet size (sorry no Linux):

My conclusion: building a line-rate gigabit router (or a few rules ipfw
firewall) is possible on commodity server without problem with FreeBSD.
Building a 10gigabit router (this mean routing about 14Mpps) will be more
complex in present day.
Note: The packet generator used was the high-perf netmap pkg-gen, allowing
me to generate about 13Mpps on this same hardware (under FreeBSD), but I'm
not aware of forwarding tools that use netmap: There are only packet
generator and capture tools available.
