My talk from this year's We Love Speed is on YouTube! 👇 In "Tight Mode: how browsers REALLY load web pages", I take a very deep/very nerdy dive into why browsers sometimes intentionally delay loading resources, why they all do it differently, and why they should *stop clowning around* 🤡 #webperf

Great talk Robin! Is there a way in RUM to detect when Tight mode ends?

Not that I know of no... Would actually be quite interesting to have that as a signal imo... @tunetheweb.com @patmeenan.com

See: x.com/csswizardry/... Though preloads for images broke all that :-) Now it's probably best to put a <script>performance.mark("body-opened")</script> user-timing entry just after <body>, which is pretty much when tight mode ends.
