We have detected a build metrics regression from push:

https://hg.mozilla.org/releases/mozilla-beta/pushloghtml?changeset=a954bf8992bdb680fb1a1b9047f2fcc1177c9e3f

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

Regressions:

0.27% installer size osx-shippable opt nightly 68,019,421.12 -> 68,205,855.42

You can find links to graphs and comparison views for each of the above tests at: https://treeherder.mozilla.org/perf.html#/alerts?id=21390

On the page above you can see an alert for each affected platform as well as a link to a graph showing the history of scores for this test. There is also a link to a treeherder page showing the jobs in a pushlog format.

This is similar to bug 1559064, only it happened 4 days earlier, on the mozilla-beta branch from that time (which was Firefox 68.0 Beta).

That push contains the same intermediates.json change that's implicated in bug 1559064.
