As author of one of the patches included in that push, we need your help to address this regression.
Details of the alert can be found in the [alert summary](https://treeherder.mozilla.org/perfherder/alerts?id=2607), including links to graphs and comparisons for each of the affected tests. Please follow our [guide to handling regression bugs](https://wiki.mozilla.org/TestEngineering/Performance/Handling_regression_bugs) and **let us know your plans within 3 business days, or the patch(es) may be backed out** in accordance with our [regression policy](https://www.mozilla.org/en-US/about/governance/policies/regressions/).

If you need the profiling jobs you can trigger them yourself from treeherder job view or ask a sheriff to do that for you.

You can run these tests on try with `./mach try perf --alert 2607`
