The Worldwide Web Consortium (W3C) announced Web Performance Working Group

W3C has announced a new Web Performance Working Group, whose mission is to provide methods to measure aspects of application performance of user agent features and APIs. As Web browsers and their underlying engines include richer capabilities and become more powerful, Web developers are building more sophisticated applications where application performance is increasingly important. Developers need the ability to assess and understand the performance characteristics of their applications using well-defined interoperable methods. This new Working Group will look at user agent features and APIs to measure aspects of application performance. Group deliverables will apply to desktop and mobile browsers and other non-browser environments where appropriate and will be consistent with Web technologies designed in other working groups including HTML, CSS, WebApps, DAP and SVG.
