This is how benchmark results would change (along with a 95% confidence interval in relative change) if bf5c500 is merged into main:

• ✔️cache_applying: 157ms -> 156ms [-4.94%, +3.71%]
• ✔️cache_recording: 561ms -> 563ms [-0.76%, +1.4%]
• ✔️without_cache: 1s -> 1s [-0.39%, +0.53%]

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