I spent the last 6 months optimizing front end performance at my last workplace. What I can say is measure before just blindly following a checklist. Chrome devtools performance and audit tools are awesome. Measure, fix biggest bottleneck, repeat. This post has some great recommendations but things could be simpler. Like use http cache headers instead of service workers. They help both the cdn and the browser. Use immutable urls for assets. The best way to improve perf is to simply load less JS and CSS. Less is more. It’s not always possible but helps trim down large swaths of network load when you can keep things simple.
