Recently Google started a new beta service to optimize the performance of websites, called PageSpeed Service. PageSpeed Service is an online service to automatically speed up loading of your web pages. PageSpeed 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.
Steve Sounders started in 2010 the HTTP archive to track how the Web is built. Trends in web technology load times, download sizes, performance scores and much more can be downloaded to present statistics.
