What is this? This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing b25b6ea (parent) -> e92ffc3 (this PR)

Test differences

Show 4 test diffs

4 doctest diffs were found. These are ignored, as they are noisy.

  3. x86_64-rust-for-linux: 3252.6s -> 2670.2s (-17.9%)
  4. aarch64-apple: 8419.7s -> 7100.1s (-15.7%)

  9. aarch64-gnu-debug: 4490.2s -> 3884.7s (-13.5%)
  10. i686-gnu-1: 8482.3s -> 7464.3s (-12.0%)
How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
