This is how benchmark results would change (along with a 95% confidence interval in relative change) if edf399c is merged into main:

•   :ballot_box_with_check:cache_applying: 161ms -> 164ms [-1.46%, +4.78%]
•   :ballot_box_with_check:cache_recording: 541ms -> 538ms [-2.02%, +1.03%]
•   :ballot_box_with_check:without_cache: 1.03s -> 1.03s [-0.47%, +1.28%]

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