I haven't looked into why, but these two are by far the slowest loading pkgs in my spacemacs:
3.4 and 4.0 seconds, with the runners up needing 0.6 and 0.5 seconds.

It also blocks the execution of my editor when opening nix files. Is it possible to run nix-build asynchronously?

nix: remove company-nixos-options
c00438c 
This package blocks emacs for several seconds or even more if no network
is available. I have not seen any way to disable it.
It is unlikely that upstream will fix this anytime soon,
hence removing this package:

nix-community/nix-emacs#28

Upstream is not working on this package anymore:

nix-community/nix-emacs#46

Thanks.
I use doom as well now.
It'd be nice if the root cause was found though.

Well. I know the root cause, the module should use the non-blocking api for executing nix-build. But my emacs-fu is not strong enough to make this happen. This is a similar problem to: wbolster/emacs-direnv#31

Also see purcell/envrc#6 for more discussion on making things asynchronous.
