Yes, it is taking full advantage of the hyperthreading. Keep in mind that hyperthreading IS NOT two separate processors. It is a parallel execution path within the processor, which can't always be leveraged. Some applications can and some can't - but there's no definitive way to say an app can or can't do it.
