Talos has detected a Firefox performance regression from push: https://hg.mozilla.org/integration/autoland/pushloghtml?changeset=72a0af4b7041879f651f2222838e41acc5ff60b5 As author of one of the patches included in that push, we need your help to address this regression. Regressions: 6% damp summary windows7-32 opt e10s 260.97 -> 277.17 5% damp summary linux64 opt e10s 232.76 -> 244.59 You can find links to graphs and comparison views for each of the above tests at: https://treeherder.mozilla.org/perf.html#/alerts?id=7444 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.

:gl Could you take a look over this developer tools perf regression and estimate a fix time for it?
This looks like it's entirely getting hit on inspector.close  - went from 85ms to 2,250ms! Maybe the panel is waiting for something async on destroy? : https://treeherder.mozilla.org/perf.html#/comparesubtest?originalProject=autoland&originalRevision=25fe56e55e611f8b6747c9378ec492b538c8ce29&newProject=autoland&newRevision=72a0af4b7041879f651f2222838e41acc5ff60b5&originalSignature=63c652b34bd8fcf3623be048bdd3104906f70f02&newSignature=63c652b34bd8fcf3623be048bdd3104906f70f02&framework=1
this seems to be fixed: == Change summary for alert #7480 (as of June 22 2017 01:14 UTC) == Improvements: 6% damp summary windows7-32 opt e10s 277.41 -> 260.53 4% damp summary linux64 opt e10s 244.25 -> 234.75 For up to date results, see: https://treeherder.mozilla.org/perf.html#/alerts?id=7480 this looks to be a merge in, but the merge from inbound has no data which shows the regression- is it possible this was fixed on mozilla-central somehow?
