Front-end Performance and WordPress

Front-end performance refers to the speed and responsiveness of a website as experienced by the user. It can be improved by optimizing images, minifying code, using a content delivery network (CDN), and reducing the number of HTTP requests, among other things.

Front-end performance in WordPress can be tricky because there are so many chefs (theme, plugins) that contribute to what the HTML document looks like. Fail to keep an eye on things and they will get out of control.

This talk is not at all about server-side performance (even though that is also important), instead, it focuses on how the user’s device processes the page returned by the server, the main challenges, tools that can help you, mistakes to avoid, and yes – because everyone cares about them – Core Web Vitals.
