Fawkes leverages our measurement study finding that 75% of HTML content remains unchanged across page loads spread 1 week apart. We built two fully-automatic systems that are complementary to each other and each optimizes one of the above contributors to slow page loads: Fawkes and Horcrux. We pursue a programmatic approach that works on legacy web pages and unmodified browsers. These scripts often make pages slow to load, partly due to a fundamental inefficiency in how browsers process JavaScript content which fails to leverage the multiple CPU cores that are readily available even on low-end phones. Next, these pages include large amounts of JavaScript code in order to offer users a dynamic experience. Inspired by mobile apps which provide faster user-perceived performance, we target two significant bottlenecks in the page load process First, clients have to suffer multiple round trips and server processing delays to fetch the page's main HTML during this time, a browser cannot display any visual content which frustrates users. Numerous solutions have attempted to optimize the web performance, however, these state-of-the-art techniques are either ineffective or impractical in real-world settings due to complexity or deployment challenges. Despite the rapid increase in mobile web traffic, page loads still fall short of user performance expectations.
