Summary

[edit]
Description
English: The Wikimedia Performance Team released a performance improvement leveraging the "preload" hint as an HTTP header to production Wikipedia on April 27th 2017. It gives a higher priority to the logo on browsers that support the preload hint. This video shows the effect on a simulated slow internet connection before and after the change.
