This is how benchmark results would change (along with a 95% confidence interval in relative change) if 1976817 is merged into main:

•   :ballot_box_with_check:cache_applying: 259ms -> 257ms [-3.58%, +2.28%]
•   :ballot_box_with_check:cache_recording: 883ms -> 874ms [-3.35%, +1.36%]
•   :rocket:without_cache: 1.68s -> 1.63s [-4.54%, -0.51%]
