Introduction

Core Enhancements, Performance

If async is not present and defer is present: The script is executed when the page has finished parsingIf async is present: The script is executed asynchronously with the rest of the page (the script will be executed while the page continues the parsing)


Improve your page loading time by allowing javascript loading asynchronously
You will see the difference with YSlow and Google Page speed ranking but your visitors will thank you for providing a speedy website.

When a browser loads a webpage, it will start by loading external Javascript and CSS ressources before loading the html and render it's content.

  • If neither async or defer is present: The script is fetched and executed immediately, before the browser continues parsing the page

This will improve your global page loading time

However, this is not applicable to all scripts as you want to make sure the script is loaded while some other script or inline script will call it.

Usually, if your jQuery inline scripts are called within a jQuery(document).ready() declaration, you can safely load the javascript file asynchronously.

Does a good job!

This plugin works exactly as described. PageSpeed and !YSlow score immediately went to 100% rating after activating and configuring.
Ease of use
Simple to use, activate plugin and add the links to the scripts being loaded by your site.
Support
Support was not needed even though the documentation is self explanatory.
Documentation
Documentation should probably tell the lesser advanced users where they can look in HTML source to view scripts being loaded by Joomla.
I used this to: Deferring and Asynchronously loading scripts on my site.

Hello, i downloaded and installed plugin pretty easy, fast and accessible
Ease of use
Its easy to use, but i need some help on how to manually configure it, i mean i enable the 2 options but still i dont know which scripts add
Support
Documentation
I hope you make a tutorial on how to use it for the non experts
I used this to: defer parsing java
Functionality
Works as expected!
Ease of use
Easy to setup, just needed to specify paths to javascripts that should be "asynced."
Support
The developer were very helpful when I had an issue with making the plugin work, and the problem got easily resolved based on his advice.
Documentation
Ok, could me some more information on troubleshooting.
I used this to: Making a bunch of javascripts load asynchronously, hereby enhancing the speed of my site.

It simply works

The plugin is not activated when installed, you have to do that manually, but that does not matter, as it wants to be configured anyway
Ease of use
It's simple and straightforward, not a big deal when it comes to make it work.
Full mark, says I.
Documentation
Is kept to a minimum - you've got to realise that you have to enter paths to you JS files without th single quotes around them.
I used this to: Used for several J!3.x sites to get better GTmetrix (and possibly Google) results. Especially when you have a load of JScript, it boosts 'Defer parsing of JavaScript' in Page Speed to near 100%

Thank you
