You can see a ~30-45% visualmetric regression for Yahoo Mail on MacOS here:

Blocks: 1689699
Blocks: 1689702
No longer depends on: 1689694
No longer blocks: 1689699, 1689702

Let's target fixing this in M7.

This is tracked as part of Fission, so I don't think tracking this also as a qf bug is particularly useful.

Whiteboard: [qf] fission-perf → fission-perf

The regression here is down from 20-40% to 7-10% with the Non-native Theming landing for mac, and the preallocation delay patch (bug 1694036). There probably are more gains that can be made here.

We should target getting this regression down to at least 5%.

Latest measurements show that this continues to be 8-10% regression on Mac, even with newer HW (Mac Mini R8’s; 6x2 core i7’s). This is within our release criteria targets and is good enough for Beta.
We'll continue looking for performance optimization opportunities for this and moving this to M8 (Release).

Fission Milestone: M7 → M8
