Performance Regression: -14.36%
⚠️ 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 benchmark measured no execution time
Nothing ran under measurement, usually because the compiler removed the code under test. This result is not comparable, so it counts as unchanged.
⚠️ 12 benchmarks spent significant time in system calls
System calls cannot be consistently instrumented, so they are not included in the measure, which understates the real cost. Please switch to the Walltime instrument to accurately measure system calls.
⚠️ Different runtime environments detected
Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.
⚡ 1 improved benchmark
❌ 5 regressed benchmarks
✅ 2195 untouched benchmarks
Warning
Please fix the performance issues or acknowledge them on CodSpeed.
