An unscientific illustration of this point:
--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(guix scripts build)
scheme@(guile-user)> ,time (guix-build "libreoffice" "certbot" "xmonad" "-n" "--no-substitutes" "--no-build-hook")
The following derivations would be built:
[...]
;; 2.724686s real time, 3.117062s run time. 0.880827s spent in GC.
scheme@(guile-user)> (version)
$1 = "2.0.13"
--8<---------------cut here---------------end--------------->8---
Compared to:
--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,time (guix-build "libreoffice" "certbot" "xmonad" "-n" "--no-substitutes" "--no-build-hook")
[...]
;; 2.224821s real time, 2.347463s run time. 0.374545s spent in GC.
--8<---------------cut here---------------end--------------->8---
Roughly an 18% speedup here.
