Hi,
Hope you're doing well. We’re wondering how the experiment is progressing.
Please let us know if there's anything we can do.
Thanks

Hi,
We will proceed with the Stable 1% experiment for this intervention.
Rationale:
-
- The MotionMark regression is well understood. I discussed
with +Camillo Bruni and we concluded that it isn't a blocker for
measuring
the impact of this intervention on Stable 1%. Howe

would it be possible to study the changes you have made in the code? is
there an associated bugid? thank you.

Hi,
We have tried Speedometer3 and MotionMark for this feature on pinpoint.
Speedometer3:

MotionMark:

+1 to double checking the benchmark
Most likely we're good as we should have at most a single idle rAF.

Very cool experiment, and happy to see positive results!
Feedback RE: "no-op frames often occupy the main thread during page load or
input handling"...
My past experience with interactions and smoothness is that no-op-raf-loops
can have more subtle effects on UX than would be predicted by just

Hey Francois,
This sounds promising. My one concern is what effect(s) this might have on
our performance benchmarking work. +Camillo Bruni for
his thoughts. We should at the very least make sure
speedometer/motionmark/etc numbers are not negatively impacted by this
change.
Cheers,
Johnny
