Bruce makes some excellent points.
I challenge anyone to get line rate UDP out of FBSD (or Linux) for a
1G NIC yet alone a 10G NIC listening to a single port. It was exactly
my frustration with UDP performance that led me down the path of
*mmsg() and netmap.
Frankly this is an opportunity for FBSD as UDP performance appears to
be a neglected area.
