As a total non-developer, I am Team Mark on this one. I do not understand the conversation around static and dynamic pages, and speed “issues” in WordPress. If I use a caching plugin, doesn’t that also output a “static” page without hammering the database or PHP or whatever else causes poor performance? How are these cached pages different from Jam Stack pages? I also don’t see performance issues in WordPress sites that are up-to-date with a good theme, minimal plugins, proper caching, PHP 7+, and a good host. I pay $2/month for a shared hosting plan, my sites have 90+ PageSpeed score, and could easily handle thousands of visitors a day if they somehow got popular (I wish!).
