Largest Contentful Paint Largest Contentful Paint — how long until the largest visible element loads. Under 2.5s is good.
27.42 s
Total Blocking Time Total Blocking Time — total time the main thread was blocked, preventing user input. Under 200ms is good.
329 ms
Cumulative Layout Shift Cumulative Layout Shift — measures visual stability. How much the page layout shifts during loading. Under 0.1 is good.
