CodSpeed Walltime Performance Report

Merging #110 will improve performances by ×25

_{Comparing add-recursive-verifier (2c857ab) with main (9a9656a)}

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.
