I don't feel like I'm an expert on this topic although I do have some experience. When I was performing a large parametric study a few years ago, I found that allocating the work as one simulation job per core was the fastest way to get the study simulations done. For your computer that would be 8 parallel runs.
One caveat is that this makes sense for a computer not being used for any other function. If you are still trying to use your computer while the simulations are being performed, you need to reserve some cores for that function. It is also important to shut down as many background processes as possible.
Overall, I would recommend some experimentation for your specific computer.
