    test-dashboard 7278554d82fa474a4e8b5c67afb009e11e41a841 --output-dir test-dashboard

Job duration changes

dist-aarch64-linux: 5834.1s -> 9008.5s (54.4%)
aarch64-apple: 4281.8s -> 5754.6s (34.4%)
dist-aarch64-apple: 5934.3s -> 7099.4s (19.6%)
dist-apple-various: 5383.4s -> 4745.7s (-11.8%)

dist-armv7-linux: 5216.3s -> 4960.1s (-4.9%)

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.
