性能测试小工具之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

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。

解压： /是转义作用
/# tar -zxf siege-2.67.tar.gz
进入解压目录：
/# cd siege-2.67/
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:
www.licess.cn
www.vpser.net
soft.vpser.net

我还没有更改配置文件到指定目录之下
执行文件在/usr/local/bin

可自行指定安装到指定目录（此部分非必须）
./configure --prefix=/usr/local/siege --mandir=/usr/local/man --with-ssl=/usr/local/ssl
mkdir -p /usr/local/siege/etc/
mkdir -p /usr/local/siege/var/
make
