This specification defines an interface to help web developers measure the rendering performance of their applications in the wild. The API provides frame performance data, as experienced by the end user on their device, to facilitate smoothness measurements (i.e. Frames per Second and Time to Frame). This is done by capturing events for main frame and impl (compositor) thread actions, and exposing them to JavaScript via the Performance Timeline.
