Cnet: Google is launching a new program called Page Speed Service that it claims can boost website load times by 25 to 60 percent. For now, selected Webmasters can use the service for free, but the company eventually plans to charge for it.
Google's Ram Ramani described how the service works in a blog post:
Page Speed Service is an online service that automatically speeds up loading of your Web pages. To use the service, you need to sign up and point your site's DNS entry to Google. Page Speed Service fetches content from your servers, rewrites your pages by applying Web performance best practices, and serves them to end users via Google's servers across the globe. Your users will continue to access your site just as they did before, only with faster load times. Now you don't have to worry about concatenating CSS, compressing images, caching, gzipping resources, or other Web performance best practices.
