Is it better to have a physical server with 1 Quad core CPU or 4 single core CPU?
Since this is a physical CPU I would guess it's best to have the 1 Quad core CPU since the cores are all internal and can communicate faster with each other than 4 single core CPU which are external to each other and therefore cannot communicate as quickly.
Is this logic correct?
Now if we apply this same question to a VMware server does it matter whether we setup the server with 1 Quad core CPU or 4 single core CPU?
Since these virtual CPU settings are all done in software does the concept of internal and external CPU no longer apply and therefore it makes no difference when allocating virtual server CPU resources?
