Seems related to one of your patches. Is there something actionable to fix this regression?
Flags: needinfo?(terrence)
Not really? At least, I don't think it's worth fixing if we don't see any performance change elsewhere -- with that small a change I'd guess it's probably just perturbed alignment. I have some other patches in this area which are just as likely to put it back, so we'll see after those land.

Check.
