9. i686-gnu-1: 8332.5s -> 7493.6s (-10.1%)
10. aarch64-gnu-debug: 4210.7s -> 3814.9s (-9.4%)

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.
