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

[Paul]

Well who wants to code it ?  I would gladly pay someone to make it work 
the way I want.  :) It needs to be able to do line rate gig-e with 64 
byte packets and 250k routes.
FBSD6 is definitely slower.
Haven't tried dragonfly.

Thanks
