We have detected a build metrics regression from push: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=8ca33f3d833974f81ea8e744b4ddfc2a811f8d8c&tochange=c77f7fe4c21b50dc7525602f9b147530e89c2e8b As author of one of the patches included in that push, we need your help to address this regression. Regressions: 3% build times linux64 opt taskcluster-c4.4xlarge tup 1,100.16 -> 1,134.02 2% build times linux64 opt plain taskcluster-c4.4xlarge 2,057.16 -> 2,102.68 You can find links to graphs and comparison views for each of the above tests at: https://treeherder.mozilla.org/perf.html#/alerts?id=13765 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.

Bug 1464235 seems the one related to this regression. If I got this wrong, please let me know. Some how, the performance results don't show up per changeset, even though I backfilled them several times from Treeherder.
The tup build is expected to regress from bug 1464235 since zipping and uploading the tup database takes a decent amount of time. However, chmanchester mentioned that we should only be uploading that artifact on demand rather than on every push. :scarrillo will add a patch to fix that. From the graph, the linux64 plain build looks like it was just a spurious incident and not a regression. Future builds were back down to the original range. I don't think bug 1464235 should've affected those builds anyway, since it's specific to the tup build.
