Details

I am experiencing a lot of slow script dialogs in Nightly on Windows-on-ARM64. Should its heuristics be tuned for certain hardware/resource constraints? Or is it due to the lack of IonMonkey on ARM64?

I mostly see this on GSuite properties; anecdotally, in descending order of frequency: Google Slides, Google Sheets, Google Docs.

Component: DOM → JavaScript Engine: JIT

Can you try collecting a profile of the slowness?

Andrew, now that IonMonkey can be turned on, do you see these notifications less/as frequently than/as without IonMonkey?

Flags: needinfo?(overholt)

In the past 24 hours of having IonMonkey on, I haven't seen any slow script warnings :)

Based on comment 5, fixing this issue as "Works for Me".
