While I agree that there is probably an overuse of frontend rendering when templating in the backend would be fine, I suspect most of the problems you see have nothing to do with that. In my experience, the number one issue with slow sites is an overuse of trackers and advertising that drags everything down.

Precisely. Using libraries / frameworks like React, Vue, Svelte, etc. adds nearly no overhead to the core functionality of whatever it is you're creating, _especially Svelte,_ since it compiles down to the bare minimum necessary to power any dynamic functionality (it doesn't ship with a complete runtime), and supports static templates and markdown out of the box.

I can say with confidence that unless I royally screw something up in my component lifecycles or render loops, everything is just as snappy as ever. No latency. No lag. Just a zippy fast web app with URL/route changes that fly, fetched data populating quickly, and interactions feeling wonderful -- and that's because said apps I'm developing _aren't_ using any heavy tracking libraries.

People are too quick to blame slow performance on modern view libraries, and even likelier: they've never used them before.
