Hi,
I have a 32 core VCPU and a ratio under 1:1 (about 0.87) and the processor is an Intel 4216 32 cores with HT
The system needs to much from the cpu because the application isn´t very performatic and has some bugs
Which is the better configuration to use in the vms
6 cores x 1 socket or 2 cores x 3 sockets or 3 cores x 2 sockets
The 4216 is a low end 16 Core CPU. With HT enabled it reports 32 logical CPU to your Hypervisor. So you ratio is > 1:1 if you leave HT out of the game. In larger farms HT add up to 25% so there is a benefit. But as often always... it depends on YOUR workload.
About the CPU configuration it doesnt make a difference as long as you stay within your NUMA Node size. I personally would avoid the 3 socket configuration it doesnt feel right. I remember in the early days of AMD 3 Core CPUs that not all OS CPU schedulers like them.
Why not just edit the CPU config and watch esxtop when performing some workload?

No. I have to read Intel ARK on regulary basis because iam a HW reseller (Dell/VMware) so iam sure you have a 16 Core CPU 🙂
If you see 64 logical CPUs you have a 2 socket system. IIRC you see better information when clicking on Host->Configuration->Processor (Its a entry in the bottom).
So with a 6 vCPU you are within your NUMA boundary which mean it doesnt matter if you select 6x1, 3x2 or 1x6.

Sorry, are you correct.
We have 2 socket
Thanks for the anwser
