:MattN I see you are the owner of bug 1387611. Can you look over these perf regressions, to improve? Or are these something we should consider accepting or backing out?
Some of this was already filed as bug 1388078 and they all have the same root cause I think.
Hi Ionuț, Do you still see the performance regression in 57?
No, these regressions don't show up on 57.
