Linux red5下压力测试根据webbench安装与使用

webbench最多可以模拟3万个并发连接去测试网站的负载能力，个人感觉要比Apache自带的ab压力测试工具好，安装使用也特别方便。

1、适用系统：Linux

2、下载编译安装：

wget http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz  
http://home.tiscali.cz/~cz210552/webbench.html
tar zxvf webbench-1.5.tar.gz  
cd webbench-1.5  
make && make install 

 3、使用： make && make install 报错

    ctags *.c  
    /bin/sh: ctags: command not found  
    make: [tags] Error 127 (ignored)  
    install -s webbench /usr/local/bin  
    install -m 644 webbench.1 /usr/local/man/man1  
    install: cannot create regular file `/usr/local/man/man1': No such file or directory  
    make: *** [install] Error 1  
      
    解决办法：  
    [root@localhost webbench-1.5]# mkdir /usr/local/man  
    [root@localhost webbench-1.5]# make && make install  

 4、测试

    [root@localhost webbench-1.5]# webbench -c 5000 -t 10 http://127.0.0.1/index.html  
      
    结果：
