Thank you very much for sharing these numbers.
Did you try to evaluate how both mechanisms scale with many VMs ?
For example, you can run:
1 VM with 2 VCPUs
then 2 VMs with 2 VCPUs each
then 3 VMs with 2 VCPUs each
...
up to 12 VMs with 2 VCPUs each
and compare the results: average performance per VM for each
configuration.
