Performance Regression: -0.86%
⚠️ 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.
⚡ 7 improved benchmarks
❌ 6 regressed benchmarks
✅ 1514 untouched benchmarks
Warning
Please fix the performance issues or acknowledge them on CodSpeed.
