BTW, standard is usually to use number of cores + 1, as this takes
advantage of the way schedulers work and also things like hyperthreading.
Actually, in my own tests (and other's) having lots and lots of threads
(like 4-5 for my single core systems) seems to be a lot faster then the
normal number of CPUs + 1. However, there's been no rigorous testing of
this phenomenon that I know of, so I'd recommend following the CPUs+1 rule.
