At the WordPress Cambridge meetup on 10th May 2021 I gave a slightly longer version of the Show & Tell talk I’d prepared for WPChelt in April. “Does my site run slow with this?” reports on attempts to measure WordPress server response, and the plugins used to visualise the results.
These are the slides for the talk.

Slide 11: Yoast meta description
I wrote some notes attempting to explain my failure to demonstrate the problem I’d previously detected when you haven’t written a meta description for each post.
I’ve never looked into the question answering “Why does Yoast SEO produce the meta output to the front end when it’s being viewed by an end user?”
Prompted by the Q & A discussion
I forgot to mention a plugin called Laps, by Andrey Savchenko; rarst/Laps. This provides a visual breakdown of processing time by hook.
WordPress doesn’t just load PHP files. It will also load many other files, some into structures in memory. Each of these will take time to load, especially if some form of parsing is performed to convert JSON into a PHP object.
