Luigi just pushed it up to eleven and demonstrated what current hardware is capable of. I have never bought the "We need eleventy cores just to push 10ge of real traffic!" before. Luigi did note down where the per-packet inefficiencies were. What we have to do now is sit down and for each of those, figure out what the root causes are and how to mitigate it. There's some architectural things that need tidying up (read: CPU pinning, queue handling, some locking hilarity) but if they're solved, we'll end up having dual core boxes push line rate packets for routing. So the gauntlet has been thrown. Let's fix this shit up. -adrian _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
