On the web, speed is everything. The responsiveness of your browser, the time it takes for a web app to appear, and how quickly that app handles user interactions all directly impact your experience as a web user. At Microsoft, we care deeply about improving web performance, and we’re making progress on it from several directions: Within the browser itself, by making Edge faster and more responsive. Under the hood, by making the browser engine run complex web apps faster. And finally, by helping web developers build faster web apps.
