I'm trying to resolve a bad page score using https://pagespeed.web.dev/ On the top part ("Discover what your real users are experiencing") there's a toggle button to choose "This URL" and "Origin", and somehow the values in "This URL" is much worse than "Origin" (which relatively match what I got if using Chrome Dev Tool)
So could somebody please enlighten me what's the difference between those two / how Page Insight got those 2 from, as well as the difference between those and the "Diagnose performance issues" section?
