Would it be possible to retrieve N longest trace sections given some criteria?
Let's say I have benchmarks on CI that track regular metrics like startup or frames.
Alternatively, I'm exploring some app and don't have much information about it.
To better understand where should I focus, I would like to understand the most impactful trace sections within a section to understand what might contribute the most to janky UI.
Technically, I could dive into the perfetto trace and create a query that would order N slices by dur, but could we do something like this from metrics?
Something like "give me 10 longest sections within Compose:recompose section` when composition tracing is enabled.
I'm not sure metric outputs would be ready for something like this and/or if this is reasonable/feasible.
