Switching to http2 should help too iirc. also, for React developers you should be using lazy loading, code splitting, and dynamic imports to ensure you are only delivering what is actually needed on any given page/route. Thankfully the app I work on at work is not used in these types of situations so bandwidth optimization has never been something we have to focus on, but getting in the habit of using those patterns from the get-go can only help when doing side work or other publicly facing mobile-ready sites.
