Performance Regression: -6.65%
⚠️ 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.
⚠️ Different runtime environments detected
Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.
⚡ 10 improved benchmarks
❌ 14 regressed benchmarks
✅ 1557 untouched benchmarks
Warning
Please fix the performance issues or acknowledge them on CodSpeed.
