> Without RSC you have to wait for the user to download the application bundle before the request for content can even be sent to the server.

This is an argument for not putting all your JS in one monolithic bundle and instead parallelizing data loading and JS loading. It's not an argument for RSC.

Even if you split up the bundle you will still need multiple round trips to the server to fetch the data.

Ignoring TLS we have:

1st RT: HTML and loader script (CDN)

2nd RT: data (app server) and code (CDN) in parallel

Therefore you need two. But not all roundtrips are equal. A roundtrip to a CDN is much faster than a roundtrip to an application server and database, unless you have some funky edge database setup.

If you render on the server, your first roundtrip is slow because the client has to wait for the application server and database before it can show anything at all. If you render on the client then your first roundtrip is fast but the second one is slow.
