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。
官方：http://www.joedog.org/
Siege下载：http://soft.vpser.net/test/siege/siege-2.67.tar.gz
解压：
# tar -zxf siege-2.67.tar.gz
进入解压目录：
# cd siege-2.67/
安装：
#./configure
# make
# make install
mkdir -p /usr/local/var/
/usr/local/var/siege.log # 日志路径
ulimit -SHn 65535 # 修改最大打开文件数(等同最大连接数)
使用
-c #是并发量
-r #是重复次数
-f #指定文本，每行都是一个url，它会从里面随机访问的
siege -c 200 -r 10 http://jj01.com/ # 单个页面
#cat example.url
http://127.0.0.1
http://127.0.0.1/index.html
siege -c 200 -r 10 -f example.url # 多个页面
