Effortless Performance Debugging

Mon, 9th – 10:55

The website is already live. You are really proud of how it turned out, but then you notice that something is off… After some time you realize that the problem might lie in performance: things take too long to load, there are moments when you see awkward content jumps and at times scrolling feels painful. Sounds familiar? This talk is for you.

During the session we will talk about the causes of painful performance and look into simple and actionable steps how to make a website more performant with a little effort. Most of the examples will be based on a real-life debugging experience. We will dive into the undiscovered areas of Developer Tools and into the basic performance auditing. I will help you understand how browser rendering works and why it can be one of the causes of flawed interaction performance. To leave you with some ideas about where to start your debugging, I will also provide you with examples of UI patterns that are bound to slow down your experience, if implemented incorrectly.
