Resolve bitpacking functions once for bitwidth - #9721
Performance Regression: -12.36%
⚠️ 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.
❌ 3 regressed benchmarks
✅ 2091 untouched benchmarks
⏩ 206 skipped benchmarks1
Warning
Please fix the performance issues or acknowledge them on CodSpeed.
