Performance Regression: -4.54%

⚠️ 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.

⚡ 1 improved benchmark
❌ 1 regressed benchmark
✅ 2102 untouched benchmarks
⏩ 461 skipped benchmarks1
🗄️ 1 archived benchmark run2

Warning

Please fix the performance issues or acknowledge them on CodSpeed.
