Right now v6 only available via http://webpagetest.org/ chromium advanced option or via Google Canary web browser. Google PageSpeed Insight public test page is still v5.
Google PageSpeed Insights now updated to use Google Lighthouse v6 Web Vital Metrics https://developers.google.com/speed/pagespeed/insights
Now we have to optimise ur site again. Before this webmasters showing moderate speed. Now everything is showing slow despite getting 70+ score.
lab metrics determine the single score number but field/origin real world metrics determine the speed rating slow/fast/moderate. That’s why you should never focus on single score number but field/origin and individual metrics themselves.
Here’s Google’s summary of the three Core Web Vitals…
Largest Contentful Paint (LCP): measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading.
First Input Delay (FID): measures interactivity. To provide a good user experience, pages should have a FID of less than 100 milliseconds.
Cumulative Layout Shift (CLS): measures visual stability. To provide a good user experience, pages should maintain a CLS of less than 0.1.
