QUIC support for lower network latency

[udhos]

Since network latency is a real obstacle for gowut responsiveness, how about adding support for QUIC protocol?

https://github.com/lucas-clemente/quic-go

Would it be very hard to include feature?

Estimation (of effort) requires investigation.

Or would gRPC be a better choice? (Don't know) http://www.grpc.io/

[udhos]

gRPC is based on HTTP2.

QUIC could reduce network latency:

Key features of QUIC over existing TCP+TLS+HTTP2 include

• Dramatically reduced connection establishment time
• Improved congestion control
• Multiplexing without head of line blocking
• Forward error correction
• Connection migration

You can already try out QUIC:

    import "github.com/lucas-clemente/quic-go/h2quic"
...
    go server.Start("")
    return h2quic.ListenAndServeQUIC(addr, tlsCert, tlsKey, nil)

You need server.Start atm as that's the one that registers the proper handlers on http.DefaultServeMux. Maybe a gwu.RegisterMux(*http.ServeMux) could help composition, but this should work, too.
