Well, let avoid to mix unrelated discussion. :-) For discussing that specific part, I reported on guix-devel my timing using ,time. comparing commit-relation using Scheme+libgit2 vs shellout plumbing= Git Simon Tournier Tue, 12 Sep 2023 00:48:30 +0200 id:865y4gz5q9.fsf@gmail.com https://lists.gnu.org/archive/html/guix-devel/2023-09 https://yhetil.org/guix/865y4gz5q9.fsf@gmail.com The result is still significantly less and discussion is welcome overthere. :-) Cheers, simon
