How to Avoid .NET Performance Problems

Every time I work with one of our .NET customers to help them with managing their application performance I come across the same problems as seen with other clients before: lots of ADO.NET queries, many hidden exceptions in core or 3rd party .NET libraries, slow 3rd party components, inefficient custom code… Too often we from dynaTrace are introduced when it is already very late in the development cycle. Most of the time we're introduced when the first performance test results show bad response times and nobody understands why it is that slow. In other cases we get called when t... (more)

Why You Can’t Compare Cross-Browser Execution Times of Selenium Tests

I am currently working on a blog where I am going to explain how to do cross-browser testing and performance analysis using dynaTrace. Before I am going to blog that How-To I want to share with you one thing that I have noticed when executing my tests in Internet Explorer 8 and Firefox 3.6. Test execution times are very different – but – this is not because one browser is slower than the other. It is because Selenium has different synchronization mechanisms in IE and FF to e.g: wait for a page to be loaded. My Environment I run a simple test on the latest 2.0 Beta build of Seleniu...

Application Performance & Architectural Problems You Can Find in an Hour

When we get engaged with prospects that are interested in our performance management solution we walk them through a Proof of Concept. We let them install dynaTrace on their own prior to the actual POC. During the POC we ask them to exercise typical use cases on their application that show performance problems. We walk them through the different analysis options and add the findings to a final POC Presentation. In this blog I want to share some screenshots and findings of a typical Proof of Concept recently done in a heterogeneous .NET/Java Environment. Out-of-the-Box Result Pre... (more)
