Note that igb is a 1Gbit/card peaking at 1.488 Mpps, which is much slower than what ipfw-user can deal with, so you do not really need multiqueue. You might find some benefits at 10G if you run multiple ipfw-user instances, one per queue, bound to separate cores (you need some small changes in the netmap I/O routines to bind to individual queues). cheers luigi > On Mon, Aug 13, 2012 at 4:08 PM, Luigi Rizzo <rizzo@iet.unipi.it> wrote: > > On Mon, Aug 13, 2012 at 02:42:43PM +0200, Olivier Cochard-Labb? wrote: > >> On Mon, Aug 13, 2012 at 1:17 PM, Luigi Rizzo <rizzo@iet.unipi.it> wrote: > >> > I just finished a netmap-enabled version of ipfw/dummynet, which > >> > runs in userspace and is able to process over 6 million packets per > >> > second (Mpps) with simple rulesets, and over 2.2 Mpps through > >> > dummynet pipes (tested on an i7-3400 connected to VALE ports; > >> > VALE is a software switch part of netmap). > >> > >> Hi, > >> > >> Reading the README file: "Real packet I/O is possible using netmap", > >> Can we use it for high-speed firewalling among real NICs now? > >> > >> Can you confirm that we just need: > >> 1.
