You don't need a frontend framework for that. Fuck people who do. They're the reason most websites are slow as molasses on my three year old phone, despite them being very basic sites. Just stuffed to the brim with unnecessary bullshit.
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.
Have you checked this is the reason? not slow network? and not ads/analytics and blocking assets? That's not exclusive to frameworks btw, and probably less likely as most optimize these things for you.
The website that is linked originally has a bunch of blocking assets.. lighthouse score is not amazing either.
Just like the original article, you might want to test your assumptions a bit more.
