Could you time just profile generation itself? To do that, you need to find the profile generation and then to rebuild it, along these lines: DRV=$(guix gc --derivers $(readlink -f ~/.guix-profile)) time guix build --check $DRV The thread contains an analysis of specific sources of slowness, such as the cost of building the XDG MIME database: https://issues.guix.gnu.org/44053 I think we’re not done; we can probably do better by first figuring out which parts take time (profiling) and then addressing specific issues.
