I got a warning about my page speed performance being suboptimal. Turns out that an iframe of 1 embedded YouTube video is loading one JS file that adds half a second to my page load.
loading="lazy" attribute to that iframe and to 2 other media assets that are further down the page. None of it seems to make any difference in PageSpeed Insights tests.
It is very annoying that PageSpeed Insights complains even about JS implementation in Google’s own scripts.
To improve general loading speeds in other geographical regions, what would be a good service to use that won’t require me to get and configure a separate server for every continent? That would help more than any optimization.
