We have detected a build metrics regression from push:

https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=80361808cf668648a20a3da2bdafb62ffbe04dd4&tochange=c43c91d2b97b1d1b230efdabce8b67d52e5cda27

As author of one of the patches included in that push, we need your help to address this regression.

Regressions:

  5%  build times linux64 opt plain taskcluster-c4.4xlarge     1,580.87 -> 1,656.01

I was actively investigating this and unaware there was a deadline to respond in order to avoid backout. This deadline would be good to include in the bug report/needinfo so people are aware of the situation. Had I been, I certainly would have reported on my progress investigating.
