Google has developed a hosted service that analyses web pages, rewrites their code to make them perform better and serves them up from Google servers, the company announced this week.

To use the Page Speed Service, publishers must sign up and point their site's DNS entry to Google. The service grabs the site's content, optimises it for speed and delivers the pages to end users.

Visitors will continue to access a site in the same way as before but could see speed enhancements of 25 percent to 60 percent, according to Google.

The service is currently being offered free to a limited number of hand-selected webmasters. Google will announce pricing and other details later. Webmasters can sign up here to receive further information when it becomes available.

Google has many products and initiatives designed to help speed up the rendering of web pages, both its own and those of other websites.

It believes a faster online experience is better for everyone, including Google, which has found in tests over the years that even small improvements in web page performance can lead to significantly greater usage.
