事务响应时间越来越大，不知道为什么

不管测试什么，事务的响应时间都是越来越大，例如刚才录了个最简单的脚步，就是打开51testing的首页，脚本如下：
#include "web_api.h"

Action()
{

lr_rendezvous("51test");
lr_think_time( 5 );
lr_start_transaction("51test");
web_add_cookie("AJSTAT_ok_pages=2; DOMAIN=www.51testing.com");
web_add_cookie("AJSTAT_ok_times=1; DOMAIN=www.51testing.com");
web_add_cookie("cdb_sid=4xiUOI; DOMAIN=www.51testing.com");

lr_end_transaction("51test", LR_AUTO);

}

controller中参数我没有修改过，都是默认的，测试结果的响应时间总是成增长趋势，如下图所示，觉得好像不太对，但是不知道什么地方问题


第一次使用LR，大家指点一下，谢谢了

不用设集合点,即使设的话位置也不对.事务里要删除思考时间.否则会干扰测试.
你是用url录制的脚本,又因为有大量的链接,图片,响应时间增加应该是正常的吧(新手推测)
建议你用html录制一下看看.

shirley1024 发表于 2009-6-17 09:09:05

集合点应该设置在哪里

lenglovelin 发表于 2009-6-17 10:04:22

建议你看看帮助文档吧 一句两句也说不清
我感觉 需要并发的时候要用到集合点
你只是打开一个网站 并不是模拟多个用户并发登录
所以应该不需要设置集合点
我也是新手 仅供参考啊

jingling410 发表于 2009-6-17 10:11:33

不设置集合点，就不能执行同时并发多少用户，去掉集合点，表示有多少人在线登录，集合点是根据你的设计要求来设置加还是不加，请你还是仔细看看文档吧，不要盲目去做，要不然你会更迷惑。

jingling410 发表于 2009-6-17 10:13:00

至于思考时间，建议不要去掉，因为他很符合实际操作，只要在最后分析结果中去掉思考时间就ok了。

受教了，谢谢各位，^_^
