Footnotes

  1. 1268 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 develop (66b85b7) during the generation of this report, so e18f6c5 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report.
