Fast but not furious: debugging user interaction performance issues

Perceived performance is not only about fast page loads and delivering the content as early as possible. It is also about all the interactions happening on an already loaded page. Even some of the most popular UI patterns can be a cause of frustration. Understanding what is happening under the browser’s hood can help you delight users with a smooth experience and avoid potential performance issues. Let’s demystify the rendering process and look into possible optimisations in order to achieve the best experience after the initial page load.

The secret web performance metric no one is talking about

After working for over a year on a project directed towards emerging markets (namely Nigeria and Kenya), I came to realise that the popular web performance metrics are all centred around a specific type of person: someone who is used to the fast and reliable connection. In my talk I want to share my experience on how to look at the overall web performance with the new metric in mind - user’s patience. I have a set of tips and tricks how to prepare for the scenario where the loading time is going to be an issue.

Demystifying web performance tooling and metrics

Web performance has been one of the most talked about web development topics in the recent years. Yet if you try to start your journey with the speed optimisations, you might find yourself in a pickle. With the tooling, you might feel overwhelmed—it looks complex and hard to comprehend.

In this talk I will lead you through the most popular web performance tooling and the metrics. There will be no more secrets around the topic and you will be able to dive into the web speed optimisations and solution research with confidence.
