  why donot support fcgi method to serve?

• go version: 1.11.2

• gin version (or commit ref): 1.30

• operating system: centos

Description

see the rel issue #673 , the reason is much slower than unix http proxy.

But, in go 1.11.2, unix http is slower than unix fcgi

go:

// fcgi usocket
func (engine *Engine) RunFcgiUnix(file string) (err error) {
	debugPrint("Listening and serving FCGI on unix:%s", file)
	defer func() { debugPrintError(err) }()

	os.Remove(file)
	listener, err := net.Listen("unix", file)
	if err != nil {
		return
	}

	os.Chmod(file, 0777)
	defer listener.Close()
	err = fcgi.Serve(listener, engine)
	return
}

nginx conf:

# fcgi usocket
location ~ ^/(\S+)/{
        #fastcgi_pass   unix:/data/usock/demo.sock;
        include        fastcgi_params;
}

# http usocket
location ~ ^/(\S+)/{
        proxy_pass  http://unix:/data/usock/demo.sock;
}
