Hardware Optimization for my VMWARE

Hi,

I'm currently running a very resource consuming Oracle product on my vmware. Luckily, I have a very geared PC for the job. However, I require the wisdom of seasoned VMware users in the following

This is my current processor:

Can someone kindly direct me as to what numbers I should be punching in terms of cores? The processor has 4 physical cores and 4 logical cores from what I understood. I tried punching in 4*4 in the settings (as a lucky guess). Didn't work out to my favor.

Thanks in advance!
