The top lists point out the specific files to fix first: the largest and slowest assets across all tested pages, and the assets returning visitors have to download again.

Largest JavaScript files

8 files

Every JavaScript byte is downloaded, parsed and executed on the main thread, so trimming the biggest bundles pays off twice.

Largest CSS files

2 files

CSS blocks rendering until it is downloaded and parsed, so the biggest files delay first paint the most.

Largest image files

10 files

Images are usually the easiest bytes to win back: resize them, compress harder or switch to a modern format like AVIF or WebP.

Short or no cache time

10 files

Assets with a short cache time are re-downloaded by returning visitors. A longer cache lifetime makes repeat visits faster for free.
