See the paper at this link to see what we did for QEMU/KVM http://info.iet.unipi.it/~luigi/papers/20130903-rizzo-ancs.pdf to make it run at netmap speeds cheers luigi > > > Thanks > Thiru. > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" > -- -----------------------------------------+------------------------------- Prof. Luigi RIZZO, rizzo@iet.unipi.it .
