Re: Speeding up networking, worth a read.

I think the dragonflyBSD team must read this, and apply the same
principles to make the DFly networking stack "super-hot".
of course we already read this paper. i quickly discussed this with
matt, and i think we agree that we don't feel comfortable with a tcp
stack in userland. on the other hand, having the stuff van jacobson
implemented in dragonfly to try out is something else, but i doubt it
would go into cvs.
we already do batch processing, basically. i think bsds always did this
due to the soft interrupt nature (i might be horribly wrong there).
while VJ shows some impressive numbers, i'm not sure how they would
apply to dragonfly. but in case you are eager to implement this, don't
let me stop you! it might turn out to be reall cool[tm], but e.g. for
tcp we already do something simmilar. we don't use these lock-free
lists, but we queue messages to ports.
but of course i appreciate your heads-up to this paper! maybe you want
to play with the network stack a little bit?
