How To Improve INP: Yield Patterns kurtextrem.de/posts/improv... by @kurtextrem.de #WebPerf #Performance #INP

Chrome 136+ ships a new V8 version that supports a "compile hint", which makes V8 parse and compile all functions in that file eagerly. Great for entry points – where you know all functions will very likely be used. Less so as 'one weird trick to make all your JS faster'.

Did you know that jQuery outperforms React, what? 😳 Sounds like clickbait, but is reality. The HTTP Archive shows 82% of sites that use jQuery have good INP on mobile📱, while only 67% do when they use React⚛️. Not just sites, also libraries. Let's fix that👇#webperf kurtextrem.de/posts/improv...

Say hello to `inverse-subset`! The idea is from a conversation with @andydavies.me at #perfnow. When you have a complete font and a subset e.g. Latin, generate another subset consisting of everything not in the original subset. E.g. all characters that are NOT Latin. npmjs.com/package/inverse-subset

is this still true, even for script type=module? 🤯 cc: @chromium.social … can’t for the life of me find the message but thank you to the person at @perfnow.bsky.social who sent this my way ❤️ web.dev/learn/perfor...

"Everyone experiences P99" - @anniesullie.bsky.social ... at subway stations, or flaky internet. Understanding & monitoring that experience can make sense. blog.chromium.org/2021/04/digg... #PerfNow

Closing talk day 2 @ #PerfNow: @anniesullie.bsky.social showing how much time improving CWVs saved. I like how Alex's great talk at the closing of day 1 was a wake-up call and now we get to see the positive side of things as contrast.

@kurtextrem.de shares thoughts on communicating performance to your boss. Thanks for the @speedcurve.bsky.social shoutouts! #performance.sync() @perfnow.bsky.social

I'll be speaking on the #PerfNow pre-conference meetup - performance.sync(). Topic: Collecting UX-impacting metrics your boss understands. Lightning talk, to spark thoughts!⚡ Looking forward to it: lu.ma/z1qt2a63

I joined Twitter when I was between 13-14, and now joining a new platform that is basically Twitter, but different, feels like really getting old. So far I like the feed though.
