I know this is *routing* WG but I figured I would try anyway. I have seen numerous comparisons and RIPE presentations on performance issues of BIRD vs Quagga vs FRR. I am looking for the same thing of switch software.  Has anyone done a feature comparison between: http://openvswitch.org/ https://www.openswitch.net/ https://cumulusnetworks.com/products/cumulus-linux/ ...any other I am missing... And even better - has anyone done a benchmark to see which performs best? Thanks, Hank
