  1. Good video. As stated, there is a real problem with iframes, which execute on the main thread. Why can't they be executed in background ? For example, if you integrate the Google One Tap Sign In / Sign up, which is a exciting feature, it loads through an iframe, blocks your main thread and destroy your responsiveness so your Lighthouse metrics.

  2. Hi, nice video. Can you provide more info, or step by step manual how to do report of histograms from Chrome UX report per months like the one at 16:57?

  3. More details on the First Input Delay (FID) metric can be found here: https://developers.google.com/web/updates/2018/05/first-input-delay

  4. Someone should show Lighthouse to Gmail team. Does not seem like there was any performance budget set for the new redesign.
