To me a performance loss similar to the one you describe would be acceptable, particularly since it should be a constant performance hit for every time ~guix import~ is called, aka it won't significantly impact long-running import commands. However, I think I may be somewhat biased on this one, so it'd be great if others could weigh in :) Kind regards, pinoaffe
