新手问题__loadrunner的controller得到的结果是这样，对吗？

夏竹 · 发表于 2010-7-23 14:07:35

我刚刚接触loadrunner，有许多疑问，在这里请教各位了。
我自定义一个脚本：web页面形式（这个存在个疑问：这个页面用到javascrip，我想选多协议脚本“javascrip+web/html”，但是在多协议设置中没找到javascrip，所以我只设置了单协议“web/html”）
场景如下：每30秒加10个用户直到加到50个Vusers为止，然后在50个Vusers下加压20分钟，之后同一时刻停止50个Vusers。我想请大家帮我分析下controller下运行的结果，该如何解释？
贴图如下。
这里：图1中，RunningVusers和Trans Response Time这两个图，中，看到vuser_init_transaction（对应脚本是登录的事务）时间很短大约15秒左右因此在图中呈现小点显示，是否可以理解成登录事务在15s内在10个用户加载时就结束了，问题是后边还有40个用户的“登录”action呢，怎么就停止了呢？然后就是对应上述两图，当成功加载50个用户后，事务数有个猛增的大值，之后为什么就平稳在4个事务数了呢，这个结果合理吗，如何得出系统的性能？
每秒点击数，有什么对性能指标来说有什么实际意义吗？

图2中，每秒的事务数，为什么平均在3个事务左右浮动呢？而单独一个用户执行（在loadrunner中）要30个事务及，这里是50个Vusers，事务数还减少了呢？
带宽这个图中，开始的几秒内，带宽达到80k而后来平稳在12k以下，是否系统出现了性能瓶颈？

另外，附上脚本代码：
