This is how benchmark results would change (along with a 95% confidence interval in relative change) if d137eb6 is merged into main:

•   :ballot_box_with_check:cache_applying: 25.9ms -> 25.9ms [-0.28%, +0.67%]
•   :ballot_box_with_check:cache_recording: 790ms -> 791ms [-0.35%, +0.66%]
•   :ballot_box_with_check:without_cache: 1.97s -> 1.98s [-0.35%, +0.54%]

Further explanation regarding interpretation and methodology can be found in the documentation.
