网站压力测试工具webbench简介、安装、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、编译安装：
wget http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz
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 500 -t 30 http://127.0.0.1/index.html
5.结果：
