高并发測试工具webbench

1.简单介绍

webbench最多能够模拟3万个并发连接去測试server的负载能力。编译和配置简单，仅基于TCP协议上对server进行測试。

Webbench也是开放源代码。从代码上看，每一个client都fork出一个进程进行測试。仅在TCP协议层对server測试。并未涉及HTTP协议。

2.安装

源代码下载: 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：假设安装过程中出现/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.測试

1分钟1000个client測试。执行命令：./webbench -c 1000 -t 60
