According this article http://lwn.net/Articles/458610/ in "tcp fast open" section:

client side: sendto( ,MSG_FASTOPEN, ..) // ref: bits/socket.h

server side: setsockopt( TCP_FASTOPEN) // ref: linux/tcp.h netinet/tcp.h

Will golang support tcp fast open natively on linux platform?

Or, what are possible solutions to use tcp fast open if I want my Go web server(net.http) use it?

I have implemented this stuff myself in golang.

It only works on linux.

Use TfoLazyDial to dial .

use TfoListen to listen on.

You need echo 3 > /proc/sys/net/ipv4/tcp_fastopen to enable this functional in your linux box.
