What's yours? I'm curious to know the SBU of a Intel i3-7100u or other i3 systems with low power consumption in mind. I'm thinking to buy a Intel NUC and to SSH into it to build LFS

If someone's interested I tried to perform a parallel make (make -j2) and the time reduced slightly:

real 3m33,793s
user 4m55,320s
sys 0m33,180s

I also tried for the sake of trying to build binutils inside QEMU without KVM or any hardware virtualization technology enabled and 1 SBU is to 208m 20s

I wonder how new Quad-Core celerons perform with parallel make
