Question

几年前我测试了node.js vs apache 2.结果令人印象深刻。 node.js非常快，尤其是高并发性。

昨天我想向某人展示......并且apch 2.4更快。

设置：

Node.js（Express.js，node 6.2.2）

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

Apache 2.4（提供php文件）

<?php
  $foo = "Hello";
  $bar = "World";
  echo "$foo $bar";
?>

我用端口80启动了apache 然后我在端口3000上启动了node.js应用程序并使用Apache Benchmark

测试了所有内容

ab -r -n 10000 -c 10 http://127.0.0.1/

结果：

Node.js的

ab -r -n 10000 -c 10 http://127.0.0.1/

如果我测试n = 1000，c = 100 ......或更高，则相同 Apache总是快两倍。

有什么改变吗？他们是否大规模地加速了apache 2.4？或者node.js变老了还是慢了？

我真的记得，只要并发度高于5或10，node.js就会更快......

我错了吗？任何评论都赞赏。

亲切的问候马丁

更新

我在网络http://zgadzaj.com/benchmarking-nodejs-basic-performance-tests-against-apache-php

中找到了这篇文章

我无法重现那些结果。当我尝试相同的设置时，Apache会更快。

Answer 1

查看2组结果。它们是一样的吗？这里有一点不同：非2xx回复：10000

您的测试结果不尽相同，因此在修复之前我们无法对性能发表任何意见。

为什么node.js比apache 2.4
