Performance degradation on some VE instances, but not on others.
Performance is negatively impacted.
This occurs on VE instances that are set up for spanning NUMA domains.
Ensure the hypervisor disables NUMA spanning on the VE guest. Specifically, restrict the VE instance to a set of cores with direct memory controller attachments. This is typically done via NUMA controls, which vary by hypervisor. For instructions on disabling NUMA spanning, see your hypervisor documentation.
