 For years there has been a stinky cloud of web performance misinformation and propaganda coming from folks in the React community. So much so that apparently a 57 score on Lighthouse is “fast” (even with 1160ms of TBT and a 5.4s LCP). (There is *some* nuance here, of course—but we haven’t graduated to those discussions yet!) If you too want to pretend that your slow web site is fast, use this handy guide: https://www.zachleat.com/web/lighthouse-deception/ 2 comments
@zachleat thanks for writing this Zach! On a project a while ago we ran into a lot of headaches trying to compare Lighthouse scores over time to track performance changes. Even the difference between running mobile lighthouse tests on a new M1 Macbook and an older Intel-powered Macbook was huge. We ended up having to change our strategy and rely more on tools like webpagetest.org. I wish there was more info out there about how device variability impacts these scores! |
