Idk how true the benchmarks hold up in reality, but lets be honest you can program a server in ANY language/framework and it will be plenty fast for any of us (as long as you dont go out of your way to do stuff very wrong).
Unless your use case is maybe very unique and or you are serving hundreds of concurrent requests (which most aren't) all day long.
And so for my conclusion, you choose what you like (which should be Go hehe).
