PHP 性能最好的应该就是原生代码了吧，真的么？MixPHP 是基于 Swoole 扩展的高性能 PHP 框架，今天我来做个对比测试，一行代码 VS 六千多行代码。

环境

虚拟机： 4 核，1G
使用 ab 工具压测，命令：ab -n 10000 -c 300 URL

原生 PHP

Apache worker模式，mpm配置如下：

<IfModule worker.c>
ServerLimit  50
ThreadLimit  200
StartServers  5
MaxClients  5000
MinSpareThreads  25
MaxSpareThreads  500
ThreadsPerChild  100
MaxRequestsPerChild 0
</IfModule>

只有一行代码，输出一个 Hello World。

<?php
echo 'Hello World';

MixPHP

默认控制器代码如下，输出一个 Hello World。

public function actionIndex()
{
    return 'Hello World';
}

开始测试

首先测试原生 PHP，QPS: 1147.96

结论

是不是测试结果让你惊讶，一行代码 VS 六千多行代码，竟然是 MixPHP 框架并发性能更强。

我来分析下原因：MixPHP 框架的核心组件全部都是常驻内存的，也就是说，六千多行代码在每次请求时，实际上只执行了其中很小的一部分代码，当然也还是要比一行代码多很多的，但是为何性能上还是要更强，这个就要归功于 swoole_http_server 了，在并发性能上他是优于 Apache 的，所以才使得 MixPHP 的性能可以超越原生 PHP。
