1.简介
webbench最多可以模拟3万个并发连接去测试服务器的负载能力，编译和配置简单，仅基于TCP协议上对服务器进行测试。Webbench也是开放源码，从代码上看，每个客户端都fork出一个进程进行测试，仅在TCP协议层对服务器测试，并未涉及HTTP协议。
2.安装
源码下载: http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5
make
注：如果安装过程中出现/bin/sh: ctags: command not found
则需安装ctags，下载地址：wget http://prdownloads.sourceforge.net/ctags/ctags-5.8.tar.gz
3.测试
1分钟1000个客户端测试，运行命令：./webbench -c 1000 -t 60
