Stephen Pate on "[Plugin: Jetpack by WordPress.com] Preload content before javascript"

Google PageSpeed insights says that JetPack javascript and HTML are slowing down my site

Is there any way to change to order of loading the page?

The exact message is

"Your page has 2 blocking script resources and 4 blocking CSS resources. This causes a delay in rendering your page."
