Why is the website slow?
This simple question can spawn a whole world of complexity, so let's take a tour through it!
We will use browser developer tools as our north star, diving into packets as well as internal net-export logs to show what's happening at every step of a web request. By translating the waterfall to the wire, we'll be able to understand common web performance bottlenecks and the quick fixes that make them disappear.
Finally, we'll take a peek at energy-aware web design to see how a website can mindfully sip power rather than burning through a battery.
You will leave this session with the tools and understanding to debug modern websites.
