2 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.

⚡ 2 improved benchmarks
❌ 2 regressed benchmarks
✅ 2000 untouched benchmarks

Warning

Please fix the performance issues or acknowledge them on CodSpeed.
