As of Autoptimize Pro 2.3 there is an option to delay all JavaScript. Delaying can have a bigger positive performance impact then asyncing or deferring because AOPro will only load the delayed JS after a to be defined delay or (better even) only at the moment user interaction (such as swiping/ scrolling or mouse movement) … Read more
