WebPagetest is a service for measuring and analyzing the performance of web pages. Users input the URL, global location, and browser type they wish to test, and WebPagetest then returns information on a number of performance factors including keep-alive, text compression, image compression, caching of static content, JS/CSS file combination, and CDN use. It also keeps track of differences between first-time and repeat viewings of a page.
