But I think in the example above La= rs was > reporting the run time of the =E2=80=98guix=E2=80=99 command when the gra= ft itself is > already built. Just the extra code to compute the graft derivation (not > actually building them) leads to x2 wall-clock time or so. yes, Ludo is right. The numbers I reported are with grafts already built, w= arm caches and local socket communication. So we=E2=80=99re only seeing the CPU-bound comp= utation here. Sorry for the confusion. I should have been more specific in the other issue.
