For those who can take advantage of it, this is really great. Easy to configure, each parameter has a clear explanation of its advantages. On my test site (a PWA) I started with a homepage that took 2.6s to load and now it’s 0.2s. All the tests (Lighthouse, PageSpeed Insights and WebPageTest) pass 100%: I couldn’t believe it! The handling of critical CSS is excellent !! Many thanks to the team behind this essential plugin.
