Thanks for the comparison
thanks for the info. Your contribution is much appreciated.
How about adding this please.
Virtual NUMA topology is available to hardware version 8 virtual machines and is enabled by default when the number of virtual CPUs is greater than eight.
Your contribution is much appreciated.
Thank you.
