Web Application Stress的Reports解析?

[yukin2003]

第一点:
Time to first byte (in milliseconds)
Time to last byte (in milliseconds)
Downloaded Content Length (in bytes)
它们里面的25th Percentile,50th Percentile,75th Percentile怎么解释?例如下面的数据:
Time to last byte (in milliseconds)
========================================================
Average: 5.00
Min: 5.13
25th Percentile: 5.13
50th Percentile: 5.13
75th Percentile: 5.13
Max: 5.13
第二点:
Page Data中的每个脚本的发送机制是怎样的?例如下面的结果:
Page Results
========================================================
URI: GET /map/gis_r1_c01.gif
Hit Count: 20
它的20次的发送机制是怎样的?也就是说"GET /map/gis_r1_c01.gif"要发20次,发完以后再去发后面的脚本;还是Page Data中的脚本是交叉发送的,测试完以后,总共统计是20次?

请大家指教!在此先谢谢了!

20次的发送是根据你设置的测试时间来测试的。如果时间长则Hit count也大一协。例如你有1000个脚本要测试，而只测试1分种，那么排在后面测试的脚本的hit count是0。

25th Percentile : The time that the pages that fall into the 25th percentile required before the last byte was received. Data measured milliseconds.
