Last June I saw an interesting conference talk at J-Spring given by Martijn Verburg (from jClarity) about the Performance Diagnostic Methodology (PDM), a structured approach in order to find the root cause of Java performance problems. In this post I will try to highlight the key concepts but I do recommend watching a recording of the talk from Devoxx UK. In the next part of this post, we will try to apply the theory to some problem applications.
On Thursday the 31st of May I went to the J-Spring conference at Utrecht, the Netherlands. J-Spring is the largest one day Java conference in the Netherlands in the spring organised by the NLJUG (Dutch Java User Group). The title of the event might be a bit misleading as you may think that it is only about Pivotal’s Spring, but it is more than that. In this post I want to share my experiences that day.
