Both are running: =E2=80=A2 on guixp9, with =E2=80=98--workers=3D2=E2=80=99 (the machine ha= s 8 cores); =E2=80=A2 on sjd-p9, with =E2=80=98--workers=3D4=E2=80=99 (the machine ha= s 32 cores). This is consistent with what I see right now at . (Now those POWER9 machines are so fast that they can beat x86_64 even with so few CPUs. :-)) Ludo=E2=80=99.
