Google has recently increased attention to Web Core Vitals (WCV) - a set of website parameters that reflect user interaction with the site, which measures not only server time, but also render time, visual consistency and visual stability of the page. Some sites have seen as much as 50% hit due to issues with Web Core Vitals! The era when you could build huge and slow pages as long as your server responds fast enough, is gone. Now it takes more than that to optimize the site. As you can see, this site running on Drupal, is close to top scores.
Core Web Vitals is a relatively new concept introduced by Google in it's search algorithm, which adds a new evaluation criteria to the search ranking. The new Core Web Vitals criteria measure how your web site performs, both load time speeds and the rendering speeds. Drupal has always been a very robust and performant system. There is no surprise that it performs so well with Core Web Vitals, making the rest of the popular CMS chase after it. Read the whole article for more details.
In the middle of its life cycle, Drupal 8 introduced in core Media, and for about a year, continued to add functionality until it became usable. Media has a library, allows reusability, and allows adding custom fields to the media entities. Some of the websites I worked with were built with the file_entity module that made the files fieldable, and entity_browser module, which provided a UI library for reusing files. That module combination is incompatible with Media and needed to be dismantled, but not before the functionality got migrated to Media. Here are some thoughts on this process.
Making Drupal into a technological marvel has cost it losing the lower segment of community, it's "soft underbelly", and Drupal has steadily been bleeding market share ever since. That is why WordPress is growing in market share, and Drupal is dropping. Here's why.
There are 3 aspects that make Drupal 8 more robust than WordPress code-wise: selective loading, quality, and caching. Generally the object-oriented code (OOP) is slower than the functional code, and having more code is slower than having less code. Drupal 8 has way more code than WordPress and it's OOP. So why did Drupal 8 beat WordPress by average 20% during my tests? Here's why.
Drupal 8 has a steeper learning curve than some other popular CMS, but it is more powerful and flexible, better suited for powerful web sites.
Some CMS are like Duplo - very easy but very limiting. Others are very flexible but you need to code a lot. Drupal is the golden middle.
