Looking in treeherder, the changeset 1dc7cd341a2a looks like it introduced the regression:
- build times debug taskcluster-c5.4xlarge: 1326.81
The changeset before (400c3278b009) has:
- build times debug taskcluster-c5.4xlarge: 758.99
The changeset after (5fdba2915ccf - where perfherder created the alert) has:
- build times debug taskcluster-c5d.4xlarge: 1348.88
Hey Sean, what do you think about the regression ?
Thanks!

hmm, the changeset shows Bug 1629738 and I don't think I am involved in this change set?

This is pretty strange to see. There wasn't a lot of new code to justify this.

Marian,
It doesn't make much sense that this patch would increase the build time on Android by 62% by itself.
Looking at the graph, it appears to be going back and forth within this range of 600 to 1800, and it didn't change noticeably after the fix for bug 1629738 was merged.
Could it be a false alarm?

Hey Dzmitry, yes i agree with that.
I'll mark this as invalid.
Thanks!
