Comparison of freeware open source switch software?

I have seen numerous comparisons and RIPE presentations on performance issues of BIRD vs Quagga vs FRR. I am looking for the same thing for freeware 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... I am familiar with: http://packetpushers.net/open-networking-cheat-sheet/ https://www.networkworld.com/article/2919599/cisco-subnet/clearing-the-fog-a... so to clarify I am interested only in bare-metal or whitebox swicthes and freeware, open source software. And even better - has anyone done a benchmark to see which performs best? Thanks, Hank
