We already had this discussion. :-) See the thread: <https://yhetil.org/guix/87o8j35ncu....@ambrevar.xyz> Compared to the previous discussion, the --profile is a good improvement since it by-passes the computations of derivations and profiles and the time of the container part still is less than 0.2s on my machine, which is acceptable, as you are saying. :-) Therefore, IIUC, your question is: how to speed up the call of Guix commands? Right? For instance, cold cache: --8<---------------cut here---------------start------------->8--- $ sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches' $ time guix environment --help >/dev/null real 0m1.730s user 0m0.845s sys 0m0.198s --8<---------------cut here---------------end--------------->8--- BTW, what about “guix run” which is faster, right?
