The new year is slowly approaching. Time to look back on the past year and set resolutions for next one. For me this usually means confirming I didn’t really achieve what I wanted to achieve, ending with a well-spirited “but next year will be my year.” But this year will be different!

Earlier this month I attended the first edition of performance.now(): a top-notch conference in Amsterdam focussed on web performance and organized by the same good folks as CSS Day and Mobilism. I learned a lot about resource loading, rendering performance, protocols (hello, HTTP/3!), and much more, and here’s my attempt at capturing some of it. Enjoy!
