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
dns-prefetchとpreconnect、そしてprefetchやprerenderとpreloadの併記 - Hail2u
dns-prefetchとpreconnect、そしてprefetchやprerenderとpreloadの併記 2014年10月より標準化作業が公開されたResource Hints仕様により、既存のrel=dns-prefetchとrel=prefetch、そしてrel=prerenderは置き換えられる可能性がある。この置き換えが起こる可能性は決して高くはなさそうなので、実装されているもののままでも構わないと思うが、link要素のrel属性は複数の値を取ることができるので、同時指定しても良い。 rel=dns-prefetchはrel=preconnectと完全に対応しているので、そのまま追加してやるだけになる。 <link href="//example.com" rel="preconnect dns-prefetch"> rel=prefetchとrel=prerenderはR

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
Historical[edit] iCab, Mozilla Application Suite, and WebTV are the first referenced browsers to support link prefetching.[8] Browsing using a Google Web Accelerator (discontinued product, may technically be called precaching) The Blue Coat proxy appliance is known to use non‑compliant prefetching. Modern browsers[edit] Mozilla Firefox supports DNS prefetching, as of version 3.5.[9] Google Chrome
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
Service Worker で prefetch - Block Rockin’ Codes
update 2015/3/31 @hirano_y_aa さんの指摘頂き訂正しました。 response.body の clone TextDecoder の利用 intro Service Worker の「オフライン以外」の利用第二弾です。 以前、 Service Worker で XHR のモック をしましたが、今回は Prefetch を実装してみようと思います。 prefetch とは 例えば /index.html が以下のような HTML だったとします。 <!DOCTYPE html> <meta charset="utf-8"> <title>title</title> <ul> <li><a href="1.html">1</a></li> <li><a href="2.html">1</a></li> <li><a href="3.html">1</a></li>
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
