Website performance matters. Research shows that if page load time increases from 1 second to 3 seconds, the bounce rate increases by 32%, which is massive. On top of that, platforms like Google Search use the Core Web Vitals set of metrics to evaluate page performance for the purposes of ranking. Therefore, we all want to build fast websites. While website performance depends on the type of hosting, a highly performant website also depends on good configuration of Drupal. In this workshop we will focus three main parts: 1. What the Core Web Vitals are and how they work 2. How to research your website's performance with the Core Web Vitals to find out where your website is lacking 3. How to improve performance of your Drupal website with configuration and contrib modules During the workshop every attendee will get a Drupal website where they can themselves research the performance and improve it with contrib modules. If time permits, we can also look at results from your own websites.
