You'll be better off writing raw PHP without classes than using Go. Go performances are raw Go. As soon as you add any framework to the party , the perfs are falling. see the gorilla test which is a Go framework.
The OP, to which I was replying, said: "see the gorilla test which is a Go framework."
I asked about the Gorilla benchmark itself, since OP seemed to say that adding something like Gorilla would slow down the Go benchmarks, which I don't agree with.
But I also didn't realize that that person was saying that there was a gorilla test, so now I'm mostly confused.
