Largest Contentful Paint (LCP) measures loading performance. It’s a measurement, in seconds, of the largest image, video, or text block to render in the viewport of the webpage. A “good” LCP is anything under 2.5 seconds.

This being said, our demo site is a whopping 64 MB, with a mobile LCP of 6 seconds on mobile.

In this case, it won’t help the LCP too much, but will improve overall performance and Speed Index.
