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.
really good information
thanks
Thanks for the such information.
