Hilarious! My colleague Fabian Krumbholz just landed 🚀 an excellent explanation of Google‘s new metric of responsiveness, Interaction to Next Paint (INP), and why it’s important. We in the #webperformance community are super excited about the metric and have been working hard either to measure it, optimize it and help people make their sites more responsive to user interaction. https://www.inp-check.com

It pays to inspect your website's CPU usage in Safari to improve #webperf and reduce energy usage. Here I spotted recurring rendering work due to infinite animations. After removing those using local overrides, I could see energy use drop.
Here's an excellent tutorial on how to use Safari's Web Inspector to debug CPU bottlenecks from WWDC19: https://developer.apple.com/videos/play/wwdc2019/513/

Looking forward to native lazy loading for horizontal scrolling (see https://bugs.chromium.org/p/chromium/issues/detail?id=1391989). Just add a bit of CSS scroll-snapping, and presto! You can ditch all those JS-powered carousels that cause a lot of overhead.

So honored to kick off this year's Web Perf Calendar! 🤩Improving web responsiveness is tricky: bottlenecks can arise from first-party and/or third-party code. I honestly love the new INP metric and look forward to more refined field measurements with INP attribution and LoAF. 🤹🏽‍♂️

WOW: Compression Dictionaries look like they’ll have a HUGE impact on the amount of data we send on websites, which will mean much less energy consumption. @PatMeenan #perfnow #sustainableweb useasdictionary.com

Great to hear @Schouten_B at #perfnow say that his biggest performance win as a browser engineer involved measuring energy use and removing a bug that was responsible for high energy consumption. Great that you keep #sustainableweb in mind! 💪🏽
