Details of the alert can be found in the [alert summary](https://treeherder.mozilla.org/perfherder/alerts?id=43708), including links to graphs and comparisons for each of the affected tests.

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 43708`
