This should act as a demo of how we would tackle performance analysis of a web page/app. It is obvious that axo.dev is a VERY simple site and would not need this kind of deep analysis in a real situation (yet).
Perform a Lighthouse audit to create a report and to get a general feel for the performance of the site. We can do that in Chromes dev tools. Make sure to run it in Incognito mode or disable all extensions that would interfere with the page.
