LoadEvent firing late

The first post is from my Chrome browser (Version 67.0.3396.79) and in the drop menu I selected to test using Chrome.

The results are similar on Firefox browser (Version 60.0.2) and selected Opera in WebPageTest.org.

On Firefox browser (and selected Firefox in WebPageTest.org) it’s a bit different - The 3 favicons are not in the LoadEvent but inside domContentLoaded. And this time /bin/resources/icons/xwiki/spinner.gif took long to load, and the result is still 35 sec to finish loading.

Ref:

IE/Edge browser Version 38.14393.1066.0 (selected Chrome to test) and strangely the first test came back with less than 3 sec to finish loading. The 2 extra tests still came out over 30 sec tho…
