nginx win32 版本静态文件测试 (Windows环境)

下载了 Nginx For Win32 的官方版本 nginx 0.7.53

进行了试用以及压力测试。

安装使用方式很简单，直接贴官方的方式：
Win32 Binaries

As of 0.7.52, Nginx is now available as an official Windows binary.

Installation:

cd c:\
unzip nginx-0.7.52.zip
ren nginx-0.7.52 nginx
cd nginx
start nginx

Control:
nginx -s [ stop | quit | reopen | reload ]

For problems look in c:\nginx\logs\error.log or in EventLog.

但要说明一下的，之前有第三方编译的 Nginx For Windows 版本，是可以加载到 Windows 服务中运行的。但在这个官方版本下该方法行不通。所以建议暂时手动启动，或者新建一个计划任务开机启动。

然后迫不及待进行压力测试。我们使用的工具是 Apache 的 ab , 测试的是纯静态页面。就是 Nginx 一装好后默认的 ：
Welcome to nginx!

测试命令：./ab -c 100 -n 10000 http://192.168.3.50:8888/
操作系统：Windows server 2003 R2
硬件配置：Xeon 2.8G X2 1G RAM
测试结果：

由测试结果所得，Nginx for windows 100 个线程每秒只能处理 93 个请求。
如果再启动多一个 ab 来压，加起来就有200个线程，ab结果相当。各端每秒处理93个请求。
但如果你再启动第三ab 进行 100 个线程压力，正在进行的2个ab 其中一个就会被服务端拒绝。

来回尝试修改Nginx的worker_processes 参数无果，修改了 Win2003 的并发线程也无果….难道 Nginx 在Windows下就只能有这么点能耐？？回头要再详细找找原因。

另外还有一个问题，当压力测试完毕了，在 windows 中查看进程会发现 Nginx 还占着 2~30 的cpu。
在命令行下 Nginx -s stop 也无法停止。必须 结束进程…..

初步尝试就这几点，希望是我个别的问题，有机会的朋友也不妨试试。
