This assumes everything is parallel-make safe. It didn't use to be, and I'm pretty sure make release is still not parallel safe on all architectures... The number of jobs in make is NOT that straightforward either. You'll have to measure to figure out the best number. On high numbers of cores, going THAT high with -j is generally counter-productive...
