This is how benchmark results would change (along with a 95% confidence interval in relative change) if 63149cb is merged into main:

•   :ballot_box_with_check:cache_applying: 18.7ms -> 18.7ms [-0.65%, +0.96%]
•   :ballot_box_with_check:cache_recording: 626ms -> 622ms [-1.59%, +0.27%]
•   :ballot_box_with_check:without_cache: 1.6s -> 1.59s [-1.58%, +1.06%]

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