- End-to-end response time analysis
Description:
The first thing to do when an application experiences performance problems is obvious: identify the root cause of the problem. Unfortunately, all too often this is where the real trouble starts. In a typical scenario where everyone is looking for the source of a performance problem, developers blame the database for poor performance, and the database administrators blame both the developers for misusing the database and the storage subsystem administrators because their very expensive piece of hardware ought to provide much better performance. And as the complexity of the application and infrastructure supporting it increases, so does the mess. Therefore, the analysis of a performance problem should start by collecting end-to-end performance data about the requests experiencing performance problems.
The aim of this session is to introduce techniques and challenges related to end-to-end response time analysis. For illustration purposes, during the session a real project on which the speaker worked is presented.
