Performance Regression: -5.77%
2 warnings
⚠️ Walltime results may be unreliableSome benchmarks used the Walltime instrument outside CodSpeed Macro Runners, which can make the results inconsistent.
⚠️ 3 benchmarks with a significant change ran in a different software environmentTheir base and head results were measured with a different OS or toolchain, such as compiler, runtime or library versions, so the changes might come from this difference rather than from the code. Open an affected benchmark to see what changed.
⚡ 4 improved benchmarks
❌ 6 regressed benchmarks
✅ 2308 untouched benchmarks
Warning
Please fix the performance issues or acknowledge them on CodSpeed.
