MOZ_PROFILER_STARTUP_ENTRIES is probably too low for DAMP. The profiler must have increased its usage of entries... It is currently set to one million, I'll try with 2 millions. https://searchfox.org/mozilla-central/source/testing/talos/talos/test.py#431 I let the perf-html team know about the increased usage of entries.
It looks like 2 millions is enough. It makes perf-html really slow to load and navigate, but at least we can see all tests! It may be useful to run DAMP against just one or a set of subtests from try. We can do that locally via `--subtest`, but that's not something we can pass to try. https://perfht.ml/2MORkx1
