# Overview

This document provides an overview of Google's effort to make the web faster.

What would be possible if browsing the web was as fast as turning the pages
of a magazine? We invite you to join us in exploring and innovating across the
entire spectrum of performance --- from Internet protocols to the browser to
website development. Together, let's make the web faster!


## PageSpeed

PageSpeed is an open-source project started at Google to help
developers optimize their web pages by applying web performance
best practices. PageSpeed started as an open-source browser
extension, and is now deployed in third-party products such as
[Webpagetest.org](http://www.webpagetest.org),
[Show Slow](http://www.showslow.org) and Google
[Webmaster
Tools](http://www.google.com/webmasters/tools)

## Instant Pages

Prerendering is an experimental feature in Chrome (versions 13 and up) that
can take hints from a site's author to speed up the browsing experience of
users. A site author includes an element in HTML that instructs Chrome to fetch
and render an additional page in advance of the user actually clicking on it.
As a web developer, you may be interested in triggering prerendering or, much
more likely, in detecting when your site is being prerendered.

## Public DNS

Google Public DNS is a free, global Domain Name System (DNS) resolution
service, that you can use as an alternative to your current DNS provider.
