Total page size too big for 3G connections
This means that the URL in question has a total byte size (of the page and all the resources) greater than 1600KB.
Why is this important?
If the total byte size of the page and all the resources is greater than 1600KB, this is theoretically too big for a time-to-interactive of 10 seconds on a 3G connection. This means that the page is very slow loading on mobile, which negatively affects user experience.
What does the Hint check?
This Hint will trigger for any internal URL for which the total byte size of the page is over 1600KB.
