pythonphp performance comparison_golang

Original title：Performance comparison of golang, python, php, c++, c, and java Golang, python, php, c+& in 2017 #43;, c, java, Nodejs performance comparison When I was working on PHP/C’/Go/Py, I had a sudden idea and wanted to make it mainstream recently. To make a simple comparison of the performance of programming languages ​​- as for how to compare – we still have to use the magical Fibonacci algorithm. Maybe it’s more commonly used or fun. Okay，talk is cheap, show me your code! Open Mac，Click on Clion and start coding！ 1. Why is the first What about Go? Because I personally am using it recently and it feels very good. package main import “fmt” func main{ fmt.Println(fibonacci(34)) } func fibonacci(i int ) int{ if(i<2){ return i; } return fibonacci(i-2) + fibonacci(i-1); } Let’s take a look with Go1.7 first&#xff1a ; qiangjian@localhost:/works/learnCPP$ go version && time go build fib.go && time ./fib go version go1.7.5 darwin/amd64 real 0m0.206s user 0m0.165s sys 0m0.059s 5702887 real 0m0.052s user 0m0.045s sys 0m0.004s Then，Look at 1.8’s： qiangjian@localhost: /works/learnCPP$ go18 version && time go18 build fib.go && time ./fib go version go1.8 darwin/amd64 real 0m0.204s user 0m0.153s sys 0m0.062s 5702887 real 0m0.051s user 0m0.045s sys 0m0 .003s…
