We'll create fresh WordPress site with WordPress Instant Articles installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Instant Articles for WordPress will let you configure DNS prefetching URLs and will automatically prerender the last 2 posts on the front page, plus next and previous posts when viewing a single post. You also have the option to pre-render sticky posts.
It is not recommended to use more than 4-5 URLs for DNS prefetching.
Enabling page prerendering will likely increase server and client (browsers) load.
Enabling subresources will let you specify URL’s to hint the web browser for high priority files, likes .JS or .CSS, for fetching these even before they appear in the HTML document.
