XF 2.0 What page speed improvements are in XF2 with regard to Javascript?

[Stuart Wright]

I can't see anything about this in the Have You Seen threads or the forums generally.

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Because of jquery, font-awesome and various addon javascripts

Your page has 16 blocking script resources and 5 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Is there any official information about the optimisations to the back end code in XF2 over XF1 which will improve performance?
Apologies if there is and I missed it.
Thanks

I'm wondering how to do this. Do you have any information on how to do it?

Most the time the render-blocking JavaScript is down to FaceBook and Twitter code for the share buttons, so it's outside mostly of XenForo control, inless you turn off that stuff.
