Performance Regression: -3.02%

⚠️ 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.

Footnotes

  1. 89 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

  2. No successful run was found on ct/row-fn-tensor-l2 (6c84e6e) during the generation of this report, so develop (1a493b6) was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
