There's nothing wrong with some good ol server side template rendering. Non trivial pages will take longer to render though.
Sure, clients load "faster" if you mean they don't actually load everything. Apples to oranges.
If a page needs to make 5 DB queries to present a bunch of data, those 5 DB queries will be faster on the server than from the browser. So will parsing the response and transforming it into HTML.
Or do infinite scrolling and only load 10 rows from the DB, where you would have to render more rows to be usable if you didn't have infinite scrolling.
