The Web Performance Working Group has published the First Public Working Draft of Resource Timing. This specification defines an interface for web applications to access timing information related to HTML elements. User latency is an important quality benchmark for Web Applications. While JavaScript-based mechanisms can provide comprehensive instrumentation for user latency measurements within an application, in many cases, they are unable to provide a complete end-to-end latency picture. While the Navigation Timing specification address part of the problem by providing timing information associated with a navigation, this document introduces the ResourceTiming interface to allow Javascript mechanisms to collect complete timing information related to resources on a document.

26 October 2010 The Web Performance Working Group has published the First Public Working Draft of Navigation Timing . To address the need for complete information on user experience, this document introduces the NavigationTiming interfaces. This interface allows JavaScript mechanisms to provide complete client-side latency measurements within applications. With the proposed interface, the previous example can be modified to measure a user's perceived page load time. Learn more about the Rich Web Client Activity .
