W3C Invites Implementations of Performance Timeline Level 2

December 8th, 2016

The Web Performance Working Group invites implementation of the Candidate Recommendation of Performance Timeline Level 2. This specification extends the High Resolution Time specification by providing methods to store and retrieve high resolution performance metric data. Accurately measuring performance characteristics of web applications is an important aspect of making web applications faster. This specification defines the necessary Performance Timeline primitives that enable web developers to access, instrument, and retrieve various performance metrics from the full lifecycle of a web application.
