PHP swoole 和 nodeJs性能分析

js出了个nodejs，我们技术老大前段时间发了个技术邮件说php支持多线程，异步，非阻塞 还打着旗号说要灭掉nodejs，官方网站上说swoole的性能已经最少也和nodejs可以媲美了，这个需要用数据说话，周末的时候有空就顺手测试了一下这两个东东！下面是测试报告哈。

首先我用127.0.0.1:8000端口测试swoole， 用127.0.0.1:1337测试nodejs

有图有真相：

测试环境：（我这是来秀电脑配置的？哈哈哈！）

处理器：2.7GHz i7

内存：16GB 1600hz DDR3

系统 MAC OS X

测试过程：下图中可以看到我开启了swoole的debug模式，会有执行日志出现，因此实际生产环境可能swoole比测试的要高

测试结果：

上面的ab测试中：以100的并发量共向接口请求5000次。

PHP和nodejs成绩都还不错，关键是Swoole的环境我用了--debug导致有很多命令会输出，暂时有不会改回去，（稍后在公司测试环境重新测试下）

Time taken for tests:   1.411 seconds共耗时

Requests per second:    3543.00 [#/sec] (mean)   

nodeJS

Time taken for tests:   1.215 seconds共耗时

Requests per second:    4116.49 [#/sec] (mean)

从测试结果来看，虽然swoole的测试数据稍微逊色了一点，但是这并不影响我对swoole的看法（况且配置可能不是很好），我觉的对于一个C语言编写的PHP，这个已经比我们目前的环境要好的多了。
