There is - by definition - more overhead in client-side rendering. Think of it this way: The server needs to first serialise data, the client needs to deserialise it, then it needs to construct the DOM to update. The server can just do the first step and things like Hotwire can add the dynamic bits you need - all overhead and extra processing is now gone. I can list a lot of websites that don't render client-side that are fast, but very few that do which are.
