好处是可以对一组url进行测试
参见 http://www.blogjava.net/crespochen/archive/2009/06/02/279573.html 和 http://baike.baidu.com/link?url=Uv0KtwM83hvFTjudQsP37FIfeUDJxMW4Kvodfk6oSTJ4B4ctpr1R6P4CGXdyMExyU7rGL2bold_aGJHwKaV2l_
郭扬提供了1.73上的应用，拷贝到/guodian/uap2，部署上Weblogic的Server-0（端口号是7010）。uap2依赖于uap_server。通过http访问是
查询
http://192.168.1.73:7010/sguap-client/SmallCase/rest/smallCase/
增加：
http://192.168.1.73:7010/sguap-client/SmallCase/rest/smallCase/insert?uuid=XXX&name=XXX
修改：
http://192.168.1.73:7010/sguap-client/SmallCase/rest/smallCase/update?uuid=XXX&name=XXX
删除
http://192.168.1.73:7010/sguap-client/SmallCase/rest/smallCase/delete?uuid=XXX
我们在1.74上做测试。
yum -y install siege #安装siege，安装不上的话，就从前面提供的URL上下载siege，再安装。
据此，写了个shell生成url

测试命令
siege -c20 -r2 -f link.out
参数说明：
-c20 并发20个用户
-r2 重复循环2次
-f link.out 任务列表：URL列表
测试结果：

Concurrency是并发数
siege还包含了一些辅助工具：bombardment，是一个辅助工具：用于按照增量用户压力测试。
bombardment link.out 5 5 10 1
这样测试，效果也良好，就是费时间。
