15 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.
⚡ 25 improved benchmarks
❌ 15 regressed benchmarks
✅ 1473 untouched benchmarks
Warning
Please fix the performance issues or acknowledge them on CodSpeed.
