I don't think this is a resounding victory for Go. It's a compiled language and yet it can only manage just over 3000 requests a second. With such a small difference in speed, I'd be better off with Python.
If you want to see some impressive figures from a compiled language, look at Haskell's snap.
web.go is very allocation heavy and unoptimized so I am unsurprised at the less-than astounding performance shown here. Also as I said r59 is very old and go has come a long way since.
Go isn't just about speed. it is also a much cleaner and simpler language than Python. Go is designed to scale programs from tens to tens of millions of lines of code.
