10 benchmarks regressed

⚠️ 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.

⚡ 14 improved benchmarks
❌ 10 regressed benchmarks
✅ 2081 untouched benchmarks
⏩ 503 skipped benchmarks1

Warning

Please fix the performance issues or acknowledge them on CodSpeed.

Footnotes

  1. 503 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

  2. No successful run was found on develop (23a59e3) during the generation of this report, so 8ff4b4a was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
