Comment (by dcf):

 In my opinion, WebSocket wins for simplicity and robustness. I don't know
 why WebRTC would have higher performance either (but I haven't tried it).
 Even WebRTC has to do a DTLS handshake, you still have overhead there.

 With a WebSocket bridge, the issue of Cgo and threads doesn't come up. We
 only use Cgo on the client, which doesn't have to scale very much. The
 proxies are running in browsers, no Cgo there. (proxy-go is another story,
 but that's orthogonal to the protocol used for the proxy–bridge link.) And
 the WebSocket bridge is essentially just an HTTPS server, like meek-
 server, which scales pretty well.
