Just peeking at your CI run here: https://github.com/git/git/actions/runs/12597967146 versus the latest run on Junio's master: https://github.com/git/git/actions/runs/12589300693 I see: job | old | new --------------------|------|------ linux-TEST-vars 11m30s 10m54s linux-asan-ubsan 30m26s 31m14s linux-gcc 9m47s 10m6s linux-gcc-default 9m47s 9m41s linux-leaks 25m50s 25m21s linux-meson 10m36s 10m41s linux-reftable 10m25s 10m23s linux-reftable-leaks 27m18s 27m28s linux-sha256 9m54s 10m31s So it looks like any change is lost in the noise (sha256 is noticeably slower, but most jobs aren't, and some are even faster). -Peff
