This link shows a many changes which are attributed to other recent commits. I think these are mis-attributed, and all of these changes caused by this PR:
https://flutter-flutter-perf.luci.app/t/?begin=1777391259&end=1777396800&subset=all

Are these changes expected and/or acceptable?

This PR seems to be a change for only the CI config. So maybe the change in the metrics are just showing a difference between the old and new configs. If that's the case, this might not be a real regression that users would see.

But some of the changes are very large regressions. A couple examples:

• Initial compile time went from 20s to 38s.
• Time to first frame went from 180s to 580s.

Does this warrant further investigation?
