This is useful, for example, when downloading a bunch of files in parallel, or other tasks that are not bound by the number of available CPUs. -* -j * +* -j * If a CPU is found that supports hyper threading, the additional cores are used. For example, an Intel Core 7i quad-core processor supports HT, thus has effectively 8 cores.

For exampe, an old dual CPU P3 doesn't report the 'physical id' section, thus if HT is disabled (why whould you do that anyway) only one processor is used.
