One problem with load test quality, almost always overlooked, is the potential for the load generator's user thread pool to sync up and dispatch queries in bunches rather than independently from each other like real users initiate their requests. A spiky launch pattern misrepresents workload flow as well as yields erroneous application response time statistics. This paper describes what a real user request timing pattern looks like, illustrates how to identify it in the load generation environment, and exercises a free downloadable tool which measures how well the load generator is mimicking the timing pattern of real web user requests.

您的 Load Generator 是否成批启动 Web 请求？

负载测试质量的一个问题，几乎总是被忽视，是负载生成器的用户线程池可能会同步和分批查询，而不是像真实用户发起请求那样彼此独立。尖峰启动模式会歪曲工作负载流并产生错误的应用程序响应时间统计信息。本文描述了真实的用户请求时序模式是什么样的，说明了如何在负载生成环境中识别它，并练习了一个可免费下载的工具，该工具可以测量负载生成器对真实 Web 用户请求的时序模式的模仿程度。
