Nick Chapman, Su-Young Hong, and I met earlier today and we’re still curious for the final word on what is going on with the
COMPONENT_FEED_REQUEST_TIME performance telemetry ping.
Nan mentioned before that this event measures “how long it takes for AS to fetch the data from the endpoint for component feed when the browser starts up”.
Looking at the average & median of this metric over time for the 66 Beta Smoke Test Part 2, there continues to be a large gap between
default variants. I would expect there to potentially be a large gap in total feed request time between variants given
complex has more content, but it’s strange that each component feed seems to take longer in
complex as well (Nick mentioned they are fetched in parallel).
I have looped Scott Downe, Gavin Suntop, Mathijs Miermans, and Nan Jiang into the conversation here at various points. Scott Downe last mentioned that he believes the event to be working correctly, just that people have slow internet:
I’m not sure this explains why
complex is so different from
default :confused: Any chance those mentioned above can take another look into this metric? I think this may involve Nan and Scott pairing together to look into it.
