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, loved it and learned a few things! Three questions: 22:05 – The third style sheet in Safari does not trigger tight mode. Is this because it takes too long to load (at +5s), or because Safari imposes a limit on how many stylesheets can be in tight mode?

1. Yeah, could be, didn't really dig super-deep into this one yet because it felt so inconsistent. 2. this was actually SO MUCH HARDER THAN IT LOOKS. I was practicing in my hotel room all night before... luckily I think @guaca.bsky.social has some skills here, so you can book us as a double act ;)
