Return owned results from the optimizer and log every parent rewrite - #10407
Performance Regression: -7.34%
⚠️ 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.
⚠️ Different runtime environments detected
Some benchmarks with significant performance changes were compared across different runtime environments,
which may affect the accuracy of the results.
⚡ 3 improved benchmarks
❌ 4 regressed benchmarks
✅ 2168 untouched benchmarks
⏩ 534 skipped benchmarks1
Warning
Please fix the performance issues or acknowledge them on CodSpeed.
