Wikipedia is wrong and generally speaking you shouldn't trust it on CS matters. Or any other subject, really. Green thread context switching is much faster than native thread switching, as long as you don't do it badly. For example, on Linux, don't use setcontext/swapcontext/etc, because they do a system call to change the signal mask.
