Patrick Meenan outlines techniques for measuring the current user experience and dynamically adjusting the content to consistently deliver a fast experience—including dynamically adjusting image quality (without a custom image server), effective lazy image loading, optionally including third-party content, and static content serving/CDN planning—dives into issues specific to slower mobile connections where how you construct and serve your content can reduce an already slow connection to one where almost no content can successfully be delivered, and explains how HTTP/2 and proxy browsers can help.
