IIS6.0环境用FastCGI模式加载php的性能测试(4)

还是用上面的方法进行简单的压力测试

ab -n 1000 -c 20 http://192.168.0.6/abu.php
模拟出总共1000个网站请求，并发20个请求，访问服务器http://192.168.0.6/abu.php 页面

如下图：

 


点击可以看到大图

注意看CPU消耗小了很多，为了确保数据相对准确，隔了一会儿又再次做了两次测试


  

这是我在服务器上的截图，我们可以发现，基本上CPU的消耗在30-40%左右。

我本机完整的记录见下面：

三、ISAPI和FastCGI两种模式对比测试的结果

根据上面的简单测试，我们可以发现，相同硬件环境下，FastCGI方式加载PHP环境比ISAPI方式加载PHP性能提高约1倍。

把服务器换成FastCGI方式加载PHP了，性能有了明显的提高。又可以继续压榨可怜的服务器，心里十分开心。
