That is a very interesting paper. Seriously, 7mpps with an
off-the-shelf Dell 2950? Even if it were -half- that throughput, for a
pure ethernet forwarding solution that is incredible. Shoot, buy a
handful of them as hot spares and still save a bundle.

Highly recommended reading, even if (like me) you're anti-commodity routing.

Various FreeBSD related guys are working on parallelising the forwarding
layer enough to use the multiple tx/rx queues in some chipsets such as the
Intel gig/10ge stuff.

1 mil pps has been broken that way, but it uses lots of cores to get there.
(8, I think?)

Linux apparently is/has headed down this path.
