⚠️ 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.

Footnotes

  1. No successful run was found on develop (faf7e42) during the generation of this report, so 52e26d1 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
