I was not aware of Long Tasks API. However it seems to have a slightly
different focus (task vs. input events). Also I am mostly interested in
First Input Delay, and it was decided some time ago to not put it in
Long Tasks API (see
https://docs.google.com/document/d/1bYMLTkjcyOZR5Jt3vrulzMSoS32zOFtwyH33f6hW_C8/edit#).

Our feedback is that this API seems reasonable, but that there's overlap with the
"long tasks" API,
and it's not clear if we need both.

Hi Webkit-Dev,
I would like to get an official position from Webkit on the Event Timing Web
Perf API.
Besides providing information about input event latency it can be used to obtain
First Input Timing metrics. This specification builds on the Performance
Timeline
specification, which is implemented in Webkit. Chrome has implemented the Event
Timing API, see the chrome status entry below.
- Specification: https://wicg.github.io/event-timing/
- Explainer: https://github.com/WICG/event-timing
- MDN: https://developer.mozilla.org/en-US/docs/Web/API/PerformanceEventTiming
- ChromeStatus: https://chromestatus.com/feature/5167290693713920
- Caniuse.com URL: https://caniuse.com/#feat=mdn-api_performanceeventtiming

Rob.
