HeadJS - The only script in your <HEAD>

Sample page with 5 SCRIPT SRC tags
Same scripts loaded with Head JS
Non-blocking loading is the key to fast pages. Moreover Head JS loads scripts in parallel no matter how many of them and what the browser is. The speed difference can be dramatic especially on the initial page load when the scripts are not yet in cache. It's your crucial first impression.
Pages no longer "hang" and there is less or zero "flashing" between pages. User only cares when the page is ready. Unfortunately current networking tools don't highlight this crucial point. They focus on the overall loading of assets instead.
Head JS can make your pages load 100% or even 400% faster. It can make the largest impact on client side optimization
