(Whiteboard: [necko-triaged])

Metrics to add:

  1. Time from Early Hints to final response
  2. Time from Early Hints to Preconnect
  3. Time from Early Hints until Preload start (ms of wasted time for headstart)
  4. Time from Early Hints Preload started until Connect back from content process (ms of headstart for the channel)

This doesn't take into considerations how the early hints affect page load time. But would be interesting to have, because we could see if we have unexpected bottlenecks in the way we handle Early Hints preloads.

A first step would be to look at the numbers in the Firefox Profiler for local testing.

Not planned anymore.
