> speed up time to first input or time to interactive you need to actually build a working page using user data, and that's often fastest on the backend because you reduce network calls which are the slowest bit.

It’s only fastest to get the loading skeleton onto the page.

My personal experience with basically any site that has to go through this 2-stage loading exercise is that:

- content may or may not load properly.

- I will probably be waiting well over 30 seconds for the actually-useful-content.

- when it does all load, it _will_ be laggy and glitchy. Navigation won’t work properly. The site may self-initiate a reload, button clicks are…50/50 success rate for “did it register, or is it just heinously slow”.

I’d honestly give up a lot of fanciness just to have “sites that work _reasonably_” back.

30s is probably an exaggeration even for most bad websites, unless you are on a really poor connection. But I agree with the rest of it. Often it isn't even a 2-stages thing but an n-stages thing that happens there.
