> What does server components do so much better than SSR? What minute performance gain is achieved more than client side rendering?

RSC is their solution to not being able to figure out how to make SSR faster and an attempt to reduce client-side bloat (which also failed)

Maybe if they compiled away their runtime like svelte and somewhat like angular, then running SSR would be faster.

SSR with CSR is a worst-of-both-worlds approach. It leads to brittle ”isomorphic” behaviors when the same code needs to handle both SSR and CSR, inevitable client-side ”hydration” mismatches and various other issues. The same code needs to fetch eagerly but minimally, but also use and update the server-provided data on the client-side.

Ultimately that so-called ”isomorphism” causes more numerous and difficult problems than it solves.
