The only difference between an asynchronous test and a synchronous one is that for an asynchronous test Mocha will wait for the done callback to be called before moving on to the next test. If the test is deemed to be synchronous, then Mocha will move on to the next test as soon as the function you passed to it returns.

An async program will simply outperform a sync program by switching between tasks whenever there is a I/O. Threads are managed by the operating system. I remember reading that threads are managed by the operating system by moving around TCBs between the Ready-Queue and the Waiting-Queue(amongst other queues).
