I wonder why most Wordpress websites can't meet Google's requirements for a "healthy" website even when they look quite usable in real life. For example
https://www.rollingstone.com/
https://pagespeed.web.dev/analysis/https-www-rollingstone-com/adieds44wz?form_factor=mobile
For speed, it has 13/100. It failed at the core Web vitals assessment.
Most little websites based on obscure frameworks that I know do much better.
Any hints for the reasons it is so slow?
