Tackling Performance Issues with YourKit by Karsten Thoms

Performance bottlenecks are often in places one would never expect and arise when code is used in a different scale than during development. To really identify where performance gets lost and could be improved, an application has to be profiled. The JDK provides already some tools like jvisualvm that could be used and come for free. However, I will show that the commercial profiler YourKit is worth consideration and should be in every developer's toolbelt. Therefore some real-world profile snapshots will be used to demonstrate how bottlenecks in code can be identified and solved.
