1643761 - Measure about:welcome performance

Status: RESOLVED FIXED

(Firefox :: Messaging System, enhancement, P2)

Description

[Punam Dahiya [:pdahiya]]

As we are working on re-writing onboarding flow, we should have some logging/telemetry or process in place that tracks about:welcome startup and time taken for first interaction

We do have various impression and event ping-centre pings already, but perhaps those shouldn't be relied on for accurate timing measurements? E.g., we could calculate on the backend the time difference between a screen impression and a button click. Or even on first load of about:welcome, we currently get…

IMPRESSION "message_id":"MULTI-STAGE-WELCOME"
IMPRESSION "message_id":"MULTI-STAGE-WELCOME_AW_GET_STARTED"
IMPRESSION "message_id":"MULTI-STAGE-WELCOME_SITES"

But I'm guessing we want various non-user behavior timings here, e.g., time from firefox startup to about:welcome load event to done react done rendering to importable sites loaded?

+1, its non-user behavior timings, from firefox startup to react done that will be most useful to know
