If the Server rendered page is not user specific and is generic for all users then it can be cached and served quickly. Then only potentially one user would experience a slowdown and you can serve much faster.

Of course then you get into the fun of cache management and invalidation.

Elixir Phoenix has a game-changing approach here because of how it compiles templates. Effectively, the static part is always cached (until the template changes), but the dynamic part is never cached. Nothing to manage.
