React itself, or Preact for that matter, is just the baseline. You still need the application itself, which in every application I’ve worked on is quite a bit bigger than the framework itself.

So you need to download the app, maybe have that app perform some fetch requests, then have the app generate html to show to the user. This is going to be slower than just retriving the resulting html directly.

If you’re in a place with unreliable or plain out bad signal, the difference will be quite noticeable.
