各大语言性能对比PK数据

这里我用的python版本是Python 3.6.2(64位)，php版本是PHP 7.0.12（64位），node版本是v6.11.0（64位），Go 1.8.3（64位），C# 基于.Net 4.0，lua 5.1.4

对比

python

import time

calNum = 100000000

def test():
    sum = 0
    for x in range(1, calNum + 1): sum += x return sum start = time.time() test() end = time.time() print(end - start) 

PHP

<?php

$calNum = 200000000;

function test() { $sum = 0; global $calNum; for ($i = 0; $i < $calNum; $i++) { $sum += $i; } return $sum; } $start = time(); test(); $end = time(); echo ($end - $start); 

nodeJS

let calNum = 200000000;

function test() { let sum = 0; for (var i = 0; i < calNum; i++) { sum += i; } return sum; } let start = new Date().getTime(); test(); let end = new Date().getTime(); console.log((end - start) / 1000);

Golang

package main

import (
    "fmt"
    "math"
    "time" ) var calNum = 200000000 func test() int { sum := 0 for i := 0; i < calNum; i++ { sum += i } return sum } func main() { start := time.Now().UnixNano() test() end := time.Now().UnixNano() fmt.Println(float64(end - start) / math.Pow(10, 9)) } 

C#

 private static int calNum = 100000000;

        static int test() { int sum = 0; for (int i = 0; i < calNum; i++) { sum += i; } return sum; } static void Main(string[] args) { double start = ConvertDateTimeInt(DateTime.Now); test(); double end = ConvertDateTimeInt(DateTime.Now); Console.WriteLine(end - start); Console.ReadLine(); } /// <summary> /// DateTime时间格式转换为Unix时间戳格式 /// </summary> /// <param name="time"> DateTime时间格式</param> /// <returns>Unix时间戳格式</returns> public static double ConvertDateTimeInt(DateTime time) { System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); return (time - startTime).TotalSeconds; }

lua

 

calNum = 200000000


function test() local sum = 0 for i=0,calNum - 1 do sum = i + sum end return sum end local start = os.time() test() local endTime = os.time() print(endTime - start)

PHP7还是比python3.6快的，不过在脚本语言中node更快,Go挺快的
