How long does your nixos-rebuild --switch take? (lemmy.ml)

I'm a beginner/intermediate in NixOS and my flake rebuild takes about 25 seconds to be finished. Most of the time is evaluating derivation for some reason and it's getting kinda frustrating having to wait when I want to add a package to my config. Has anyone the same problem or is it normal that it takes this long in Nix?

While it obviously depends, it really only depends on how much your building from source. For me its about 1min on a low power processor.
