Webbench是知名的网站压力测试工具，它是由Lionbridge公司（http://www.lionbridge.com）开发。

Webbench能测试处在相同硬件上，不同服务的性能以及不同硬件上同一个服务的运行状况。webbench的标准测试可以向我们展示服务器的两项内容：每秒钟相应请求数和每秒钟传输数据量。webbench不但能具有便准静态页面的测试能力，还能对动态页面（ASP,PHP,JAVA,CGI）进 行测试的能力。还有就是他支持对含有SSL的安全网站例如电子商务网站进行静态或动态的性能测试。

Webbench最多可以模拟3万个并发连接去测试网站的负载能力。

官方介绍：

Web Bench is very simple tool for benchmarking WWW or proxy servers. Uses fork() for simulating multiple clients and can use HTTP/0.9-HTTP/1.1 requests. This benchmark is not very realistic, but it can test if your HTTPD can realy handle that many clients at once (try to run some CGIs) without taking your machine down. Displays pages/min and bytes/sec. Can be used in more aggressive mode with -f switch.


1、WebBench安装：

wget http://home.tiscali.cz/~cz210552/distfiles/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5
make
make install

在centos 6.3 下执行make的时候会有以下错误信息：
[root@localhost webbench-1.5]# make
cc -Wall -ggdb -W -O   -c -o webbench.o webbench.c
webbench.c: In function ‘alarm_handler’:
webbench.c:77: warning: unused parameter ‘signal’
cc -Wall -ggdb -W -O  -o webbench webbench.o  
ctags *.c
/bin/sh: ctags: command not found
make: [tags] Error 127 (ignored)
这是因为系统缺少ctags包，执行yum install ctags 安装ctags，然后执行make clean 之后再执行make
[root@localhost webbench-1.5]# make
cc -Wall -ggdb -W -O   -c -o webbench.o webbench.c
webbench.c: In function ‘alarm_handler’:
webbench.c:77: warning: unused parameter ‘signal’
cc -Wall -ggdb -W -O  -o webbench webbench.o  
ctags *.c
执行make install 安装
[root@localhost webbench-1.5]# make install
install -s webbench /usr/local/bin
install -m 644 webbench.1 /usr/local/man/man1
install -d /usr/local/share/doc/webbench
install -m 644 debian/copyright /usr/local/share/doc/webbench
install -m 644 debian/changelog /usr/local/share/doc/webbench

2、WebBench使用：
[root@localhost webbench-1.5]# /usr/local/bin/webbench -c 300 -t 30 http://www.qq.com/
