ci在并发压力测试时，表现不大好

用apache的ab工具
ab -n 1000 -c 10 http://localhost
控制器只是默认的：
public function index()
    {

      $this->load->view('welcome_message');

    }
结果为：

C:\Apache2.2\bin>ab -n 1000 -c 10 http://localhost/

每秒只能处理74次请求，这正常么？

性能测试可以参考 http://codeigniter.org.cn/forums/thread-419-1-1.html

这个测试不具有实际意义，这个关键还是看人吧。
