OK.

Without more info, it=E2=80=99s hard to tell, but there are derivations tha=
t are
marked as =E2=80=9Cnon-offloadable=E2=80=9D, essentially because it=E2=80=
=99d take more time to
transfer them and build them remotely than to build them locally.  Among
those derivations are profiles (built by =E2=80=98guix package=E2=80=99) an=
d many of the
small items built by =E2=80=98guix system=E2=80=99.  It could explain what =
you=E2=80=99re
seeing.

Something like =E2=80=98guix build libreoffice --no-substitutes=E2=80=99 sh=
ould be
offloaded, provided --max-jobs is appropriate as discussed before.

HTH,
