We can't start 2 netmap's pkt-gen simultaneously as example. cf my report: https://lists.freebsd.org/pipermail/svn-src-head/2016-December/094418.html =E2=80=8B > > b.1) netmap-fwd is admittedly single-threaded and does not support IPv6. > These clearly showed in our tests, as we were unable to achieve over 2.5 > mpps, saturating a single CPU and letting the others fall asleep. > However, bumping a single CPU queue from around 0.6 mpps to 2.5 mpps is > nothing to ignore, so it could be useful in some cases. > =E2=80=8BSoftwares using netmap are not easy to use: - netmap-ipfw (https://github.com/Netgate/netmap-fwd) was not updated since dec 2015. - And I don't reach to compile netmap-ipfw too ( https://github.com/luigirizzo/netmap-ipfw). Yes, these two ones are unmantained afaik. =E2=80=8B > c) The routing improvement project USB stick performed incredibly, > achieving 8.5 mpps out of the box.

Then for resuming: there are 3 alpha-stage but very promising projects, but they seems stuck because not enough manpower for finishing them.
