Troubleshooting of performance problems is very often - if not almost always - viewed as a reactive activity. Frankly, I have often seen it done in such a reactive fashion as a firefight; however, effective troubleshooting should build upon a solid diagnostic process. If you handle troubleshooting as if firefighting rather than based on solid diagnosis, this inevitably is a sign you have failed to take the right proactive measures. The goal of troubleshooting is to resolve an immediate performance problem - ideally yesterday. As some might expect this does not start when the problem occurs: troubleshooting done right means having a defined process as part of your performance management activities. While we try to avoid this situation as often as possible, we have to acce... (more)

JPA Under the Hood

Java Developer Magazine on Ulitzer I recently spoke on the behavior of different JPA frameworks at W-JAX(Germany) and TheServerSide Java Symposium (Prague). As some people have asked me, I am publishing the samples as well. I would also give away the Eclipse project, however, with all the third-party libraries I am sure I will end up not doing it correctly. In addition, I can add some com... (more)

A Step-by-Step Guide to dynaTrace AJAX Edition

  The dynaTrace AJAX Edition has been out there as an Alpha for a couple of weeks. It gave you the first impression what was to come. All the feedback we have received (like that from Steve Souders, and all that has come in via the contact form and the online forum) in that time made it possible to improve the tool from its early versions to its first "official" release version. In this ... (more)

This week I presented at W-JAX on Performance in AJAX Applications. You can find the slides here. View more presentations from Alois Reitbauer. Additionally I propose everybody to try dynaTrace AJAX Edition for analyzing AJAX performance in Internet Explorer ... (more)

Performance Considerations in Distributed Applications

Java Developer Magazine on Ulitzer Distribution and communication between applications and services is a central concept in modern application architectures. In order to profit from distribution you have to keep some basic principles in mind – otherwise you can easily run into performance and scalability problems. During development these problems often do not surface.  Then suddenly in l... (more)
