vmotion performance issue

Dear all,

On a five hosts cluster managed with vcenter 6.0.0, we lose a host due to netwark hardware failure.

The cluster is composed of different DELL R720/R730 servers, with differents CPU capacities (16x2,6GHz to 16x3,2GHz).

After the host failure (16x3,2GHz), some Vms were hosted on less CPU powered hosts (16x2,6GHz), and performance decreases. I suppose that 4vCPUs VMs on 16x3,2GHz are mot efficient than hosted on a 16x2,6GHz host, am I right?

If so, is there a way to ensure eqaul performances on each host of an heterogeneous host cluster?

Thank you for your responses and feadbacks,

Thomas

Refer article: https://kb.vmware.com/kb/1005764, Check under: If I add newer hardware into an EVC-enabled cluster with a lower EVC mode, do I lose performance
