Not sure what is the regressing bug.
Jetstream2 is a lower priority benchmark, and the regression is only on a sub-test. Feel free to WONTFIX.

Not sure if there is anything to see here. On central there seems to be no regression at all (but we have only one data point so far). Randell, maybe you know better how to interpret this? I tend to WONTFIX.

[Randell Jesup [:jesup] (needinfo me)]

Definite regression (on this JS2 subtest), by around 8%.
95% certain this is the PGO training change for SP3

Thanks, I was confused by the comparison being with chrome, not firefox on central, actually.

:fdoty could this be triaged?
Fx122 is now in beta, wondering if this can be investigated/fixed in the for release

Comment 9

[Marc Leclair [:mleclair]]

I think marking this as WONTFIX should be okay. My thoughts are the following (feel free to correct me!): We got an increase of 1.5% overall on sp3 after landing this whereas this regression is on a subtest of jetstream. I think the trade-off is okay for what we got.
