为什么node.js比Apache 2.4慢得多

Question

几年前，我测试了node.js和apache2。结果令人印象深刻。 node.js确实非常快，特别是具有高并发性。

昨天我想向某人展示，.. outch apache 2.4快得多。

设置：

Node.js（Express.js，节点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";
?>

我使用端口80启动了apache，然后在端口3000中启动了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/

结果：

如果我测试n = 1000，c = 100 ...或更高，则相同，Apache的运行速度总是两倍。

有什么变化吗？ 他们是否大大加快了Apache 2.4的速度？ 还是node.js变老变慢了？

我真的记得当并发高于5或10时，node.js会更快。

我说错了吗 任何评论表示赞赏。

亲切的问候马丁

UPDATE

我在网站http://zgadzaj.com/benchmarking-nodejs-basic-performance-tests-against-apache-php中找到了这篇文章

我无法复制这些结果。 当我尝试相同的设置时，Apache速度更快。

查看2组结果。 他们是一样的吗？ 这里有一个区别：非2xx响应：10000

您的测试结果是不同的，因此，在解决该问题之前，我们无法谈论性能。
