Regression Detector Results
Run ID: 47d62712-286f-466a-91c3-d07d0916b8f7 Baseline: 57c16d2ff86cf11c0abfed5c4f929dd1cbc492b3 Comparison: a01e17e3c9ca58f1f3f2a74fc318a2bcc5b086bb Total CPUs: 7
Performance changes are noted in the perf column of each table:
- ✅ = significantly better comparison variant performance
- ❌ = significantly worse comparison variant performance
- ➖ = no significant change in performance
Experiments with missing or malformed data
- basic_py_check
Usually, this warning means that there is no usable optimization goal data for that experiment, which could be a result of misconfiguration.
No significant changes in experiment optimization goals
Confidence level: 90.00% Effect size tolerance: |Δ mean %| ≥ 5.00%
There were no significant changes in experiment optimization goals at this confidence level and effect size tolerance.
Experiments ignored for regressions
Regressions in experiments with settings containing erratic: true are ignored.

Explanation
A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".
For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:
-
Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.
-
Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.
-
Its configuration does not mark it "erratic".

The process '/usr/bin/git' failed with exit code 1
To backport manually, run these commands in your terminal:
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-backport-testing backport-testing
# Navigate to the new working tree
cd .worktrees/backport-backport-testing
# Create a new branch
git switch --create backport-23210-to-backport-testing
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 03309d57ed08489b1235e84547c236cb502cc3b6
# Push it to GitHub
git push --set-upstream origin backport-23210-to-backport-testing
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-backport-testing
Then, create a pull request where the base branch is backport-testing and the compare/head branch is backport-23210-to-backport-testing.
