I'm about to release a patch to Andre that should allow if_em to fast
forward 1mpps or more on his hardware, using no shortcuts or hacks other
than the inherent shortcut that the ffwd code provides.  The approach
I'm taking also works on the other high performance network interfaces.
There is also a lot of work going on to streamline the ifnet layer that
will likely result in several hundred nanoseconds of latency being
removed from there.  I'd personally love to see DragonFly approach this
level of performance.  Given that it took FreeBSD about 3-4 years to
slog through setting up and validating a new architecture before we
could start focusing on performance, I think that DFly is right on track
on the same schedule.  Hopefully the results are as worthwhile on DFly
in the future as they are on FreeBSD right now.
