Preserve Boolean buffer handles during mask reduction - #10018
Performance Regression: -21.38%
⚠️ 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.
⚠️ 4 benchmarks measured no execution time
Nothing ran under measurement, usually because the compiler removed the code under test. These results are not comparable, so they count as unchanged.
⚠️ 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
❌ 4 regressed benchmarks
✅ 2227 untouched benchmarks
⏩ 329 skipped benchmarks1
Warning
Please fix the performance issues or acknowledge them on CodSpeed.
