there is a build times change as a result of push f5090987b7c6 on inbound: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=fcb7f6fbe3ba&tochange=f5090987b7c6 I assume it is related to that change, but it could be elsewhere, you can see the pattern of change here: https://treeherder.mozilla.org/perf.html#/graphs?timerange=2592000&series=%5Bfx-team,1475a04eb1cb14461eaf5e439a6fd435d0f78184,0%5D&series=%5Bmozilla-inbound,1475a04eb1cb14461eaf5e439a6fd435d0f78184,1%5D&series=%5Bmozilla-central,1475a04eb1cb14461eaf5e439a6fd435d0f78184,0%5D&zoom=1458484586503.9841,1458654712021.9124,368.0297397769518,3669.1449814126395&selected=%5Bmozilla-inbound,1475a04eb1cb14461eaf5e439a6fd435d0f78184,28877,24282464%5D not sure if we are really interested in fixing this, but we should be aware of it :)

Interestingly, if I overlay the build times on central there's an improvement when that merges. It's almost like we're doing more complete builds on inbound, but those builds are faster, which we also see in the more complete builds on central.

Actually, looking more closely at the graph, the new norm is established around the time of bug 1251713, so there may be a submission confusion (like bug 1261081 at play here).

IIRC we have sccache enabled on inbound but not central. So inbound build times should be shorter than central's.

Clicking on a few of the "job" links on the points with high values, they were all taskcluster jobs. We don't use sccache on taskcluster, btw (bug 1207573)

Sounds like this was just us mixing Taskcluster (without sccache at the time) and Buildbot build data. We fixed that in bug 1315041.
