It's Xeon from three yeas ago (8 real cores). It's 4 mins because our
build is not very parallel.
But that said I think what matters it the total CPU time (here ~30min)
to be compared against the same for the vanilla build (~12min). This is
about what one would get at -j1.
This indicates a 2.5x.

It's just the current way to say not to compile AoT all the Emacs
distribution but only what goes into the dump. Is going to to be the
default soon as agreed.
