Question

Loading external javascript via async script tag at the end of a webpage

I\'m trying to find out what is the best way to load javascript in terms of page speed.

Answer 1

Did I get u right? You are comparing sync with async using just one stream? That's waste of time, because of course the sync approach is faster.

Just load dozens of files at a time and u will see, that the async way is much faster, since they are loaded in parallel, not in sequence.
