标题: loadrunner报告Transaction Response Times与Average Transaction Response Time
loadrunner8.1分析word报告中Transaction Response Times与Average Transaction Response Time的说明都是Displays the average time taken to perform transactions during each second of the load test. This graph helps you determine whether the performance of the server is within acceptable minimum and maximum transaction performance time ranges defined for your system.
但里面报告出来的值不一样。

Transaction Response Times的值如下：
Color Scale Measurement Min. Ave. Max. SD
1 Action_Transaction 7.257 183.038 1527.16 344.901
1 paper_page 2.956 80.083 625.429 138.328
1 vuser_end_Transaction 1.271 39.161 222.709 64.254
1 vuser_init_Transaction 3.232 8.856 15.84 3.633

Average Transaction Response Time如下：

Color Scale Measurement Graph's Min. Graph's Ave. Graph's Max. Graph's Median Graph's SD
1 Action_Transaction 12.214 673.78 1527.16 693.198 500.21
1 paper_page 9.338 323.164 625.429 442.541 212.18
1 vuser_end_Transaction 35.903 117.342 198.781 198.781 81.439
1 vuser_init_Transaction 7.862 9.41 12.182 8.186 1.965

Transaction Response Times与Average Transaction Response Time分别到底是什么含义呢？谁能解答一下。

因为在Transaction Response Times里面是场景运行时记录的响应时间的最大值最小值与平均值，而Average Transaction Response Time 是按照采样率每隔几秒钟取一个值画出来的图，然后根据图来记录最大值最小值和平均值，在报告中也可以看到，Average Transaction Response Time中写的是图最大值、图小值和图平均值。如果将采样率设置小一些，这两个值就会比较接近。具体方法是右键点击平均事务响应时间图，选择设置粒度，就可以了，英文是set granularity

2L正解，抽样率是关键
