Week 4 – Why "top ten" Performance Reports are not the final answer

In this post I will address top ten reports and their usefulness in performance engineering. Regularly I hear people saying: “Can you show me the top ten database statements” or something similar. Their approach to performance engineering is to look at the slowest or most time-consuming statements and then make them faster. While this is not necessarily bad, there are a number of considerations to this approach which might make… read more

Week 3 – Myths and Truths about Performance Measurement Overhead

In this third article of my Performance Almanac I discuss the role of overhead in performance management. As a performance management solution provider we’re frequently asked “How much overhead does your solution have?” This question is however a bit more complex to answer than just giving a single number.

Week 1 – The Proactivity of Troubleshooting

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 as a firefight; however effective troubleshooting should build upon a solid diagnostics process. If you handle troubleshooting as if firefighting rather than based on solid diagnosis, this inevitably is a sign you have not taken the right proactive measures. The goal… read more

Understanding Internet Explorer Rendering Behaviour

Rendering is one of the key influencers of the perceived performance in web applications. In order to optimize the rendering behaviour of a web application you have to first understand how rendering works in the browser.
