Preload image: network order different between Chrome and WebPageTest

[Salmen_Bejaoui]

Hi all, trying to improve LCP I’m implemented the link preload for image and set fetchpriority to high.
Seems that Chrome and WebPageTest does not have same network order.
On Chrome the image is loaded after font as fourth request. On WebPageTest the image is loaded after all js file (I’m using Next.js v13).

Any idea why the request order are different?
Thank you

WebPageTest sorts the requests by when they are sent on the wire vs when they are discovered. Since it is on a separate origin, the time to set up the connection to the other origin introduces a delay before the request can be sent.
