In a recent HTTPArchive Almanac article about CMS use worldwide, the author mentioned that all platforms score great on the First Input Delay (FID), a Core Web Vitals metric and that Google is working on a new metric, which one might presume may replace First Input Delay (FID).
Every year the HTTPArchive publishes multiple articles about the state of the web. Chapter 16 is about content management systems (CMS). The article was written by a Backend Group Manager and Head of Web Performance Wix engineer and reviewed and analyzed by various Googlers and others.
The article raised an interesting point about how the First Input Delay metric has lost meaning and mentioned how Google was developing a new metric.

The thing about FID is that all major content management systems, like WordPress, Wix, Drupal and others all have lightning fast FID scores.
Everyone Wins An FID Trophy
The article first mentions that most CMS’s score exceptionally well for FID. And the platforms that score less well still have relatively high scores that lag behind by only 5 percentage points.
