How the Browser Pre-loader Makes Pages Load Faster
The pre-loader (also known as the speculative or look-ahead pre-parser) may be the single biggest improvement ever made to browser performance. During their implementation Mozilla reported a 19% improvement in load times, and in a test against the Alexa top 2,000 sites Google found around a 20% improvement. It’s not a new browser feature but some seem to believe it’s Chrome only and yet others sug

Prerender and prefetch support
Use prerender and prefetch in Internet Explorer 11 to improve your website's navigation. Prerender (also called preload) specifies a webpage to be loaded (rendered) in the background while the user reads the current page and prefetch identifies resources to be downloaded in the background. Because both features download content before it's needed, the resources are instantly available when needed
Link prefetching - Wikipedia
Link prefetching allows web browsers to pre-load resources. This speeds up both the loading and rendering of web pages. Prefetching was first introduced in HTML5. Prefetching is accomplished through hints in web pages. These hints are used by the browser to prefetch links. Resources which can be prefetched include: JavaScript, CSS, image, audio, video, and web fonts. DNS names and TCP connections
Resource Hints
Resource Hints allow us to help the browser find the resources it will need, and download them ahead of time for better performance. For modern websites, optimizing speed requires more than just minimizing the initial download size and critical rendering path. We can optimize the loading of resources by resolving and prefetching them as early as possible. “Prefetching†is simply the act of startin
DNS Prefetching
Problem DNS resolution time can lead to a significant amount of user perceived latency. The time that DNS resolution takes is highly variable. Latency delays range from around 1ms (locally cached results) to commonly reported times of several seconds. Solution DNS prefetching is an attempt to resolve domain names before a user tries to follow a link. This is done using the computer's normal DNS re

Prebrowsing | High Performance Web Sites
November 7, 2013 2:41 pm | 20 Comments A favorite character from the MASH TV series is Corporal Walter Eugene O’Reilly, fondly referred to as “Radar†for his knack of anticipating events before they happen. Radar was a rare example of efficiency because he was able to carry out Lt. Col. Blake’s wishes before Blake had even issued the orders. What if the browser could do the same thing? What if it
