We don't know how many cores the user will have and how many are virtual (hyperthreading). Due to the direction hardware is heading, I think if we estimate and hard code it in the design, it will soon be an underestimate. Therefore, I would probably err on the side of more threads than is typical in a server today when designing a multi-threaded architecture.
