I am not sure where to post this.
I am a bit confused on when creating a VM you now get an option to choose number of sockets or number of cores. Ie 4 socket 1 core, or 2 socket 2 cores.
I have heard different reasons from different vmware trainers 
From it is only for licensing it doesn't matter. To it must match your numa configuration or you will have performance issues.
To me I always thought it was just 4 cores for vm--no matter how it got there.
Could someone explain this to me please.
