Multi-threaded does not mean that computations are performed in parallel automatically. There are some packages around that help you to parallelize your code (e.g. the meta package "snow" that needs some additional low-level package for the architecture you are going to use for making your computations parallel). I'd use all of those packages under Linux or similar OS rather than Windows.
