It's only more performance if you're using the threading primitives and spawning new threads, moving work to them to do in parallel, etc.--this isn't something any beginner will consciously be doing. It might actually be slower in regular single process use that 99% of python users use (since the GIL is there for a very good reason and synchronizing access to python's internal state doesn't just happen for free or without some cost somewhere).
