Thank you for the opportunity to help you with your question!
Response times are in many – if not in most – cases the basis for performance analysis. When they are within expected boundaries everything is ok. When they get to high we start optimizing our applications.
So response times play a central role in performance monitoring and analysis. In virtualized and cloud environments they are the most accurate performance metric you can get. Very often, however, people measure and interpret response times the wrong way. This is more than reason enough to discuss the topic of response time measurements and how to interpret them. Therefore I will discuss typical measurement approaches, the related misunderstandings and how to improve measurement approaches.
Please let me know if you need any clarification. I'm always happy to answer your questions.
