Profilers are absolute beasts. And profilers might prove useful to pinpoint the performance issues in your Java applications.

By using profilers, developers are fortunate to find the root cause of an issue at hand. However, it requires effort to actually comprehend the data collected by the profiler. Due to the inherent complexity of the data, one has to understand how this data is collected. And thus understand how the profiler actually works.

During this talk we will go through the classic profiler features. What is a hotspot? What is the difference between sampling and instrumentation from the profiler point of view? What are the problems with either of those methods? What is the time budget of the application? And more!

I will also showcase a new kid on the block among the profiling tools: XRebel. This tool provides insight into application behavior and permits the developers to discover application level issues
