基于linux的3款压力测试工具：Siege,webbench,ab
基于linux的3款压力测试工具：Siege,webbench,ab
1.Siege
一款开源的压力测试工具，可以根据配置对一个WEB站点进行多用户的并发访问，记录每个用户所有请求过程的相应时间，并在一定数量的并发访问下重复进行。
获取：http://www.joedog.org/
官方提供ftp下载
解压：
# tar -zxf siege-latest.tar.gz
进入解压目录：
# cd siege-2.65/
安装：
#./configure ; make
#make install
使用
siege -c 200 -r 10 -f example.url
-c是并发量，-r是重复次数。 url文件就是一个文本，每行都是一个url，它会从里面随机访问的。
example.url内容:
http://www.taoav.com
http://www.tuhaoduo.com
http://www.tiaonv.com

2.webbench
获取并安装
wget http://home.tiscali.cz:8080/~cz210552/distfiles/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5
make && make install
如果找不到源就网上搜个吧
使用：
webbench -c 500 -t 30 http://www.taoav.com
参数说明：-c表示并发数，-t表示时间(秒)
