There may be more than 1 regression here. Difficult top say as the test is run on mozilla-central so not sure how to do backfills.

This is going to be caused by bug 1943696, which regressed our baseline compilation speed for nightly-only due to some new profiling instrumentation. Bug 1949824 partially addressed the regression. The rest of the regression I think we should just take because it's nightly only.
