Explanation
Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%
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
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".

What does this PR do?
pkg_sizemethodMotivation
Concerning the report update, we are currently facing PR changing no code and reporting warnings because the package size diff is not 0.
This is due to 2 causes:
minimized-btfs.tar.xzcan vary because of metadata (timestamp)Describe how you validated your changes
Updated the unit tests associated
Possible Drawbacks / Trade-offs
With this we hide small updates on the package size that could be caused by other origin than the 2 listed above. We have on-going threads to be able to get rid of these 2 constraints, so we will have to deactivate this rounding to be as precise as possible
