Performance Regression: -16.48%

⚠️ 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.

❌ 4 regressed benchmarks
✅ 1509 untouched benchmarks

Warning

Please fix the performance issues or acknowledge them on CodSpeed.
