Reserving 1 physical CPU core for Unity Connection?

Starting from VMWare ESXi 5.5 and Unity Connection 10.5.2, you no longer need to reserve 1 CPU core for Unity Connection.  Please see the URL and text below:

Quote:
"VMWare release 5.1 and older, requires reserving one physical core per physical server - see co-residency policy. With VMWare release 5.5 and later and Unity Connection release 10.5.2 and later while utilizing the latency sensitivity feature, you may remove the requirement of dedicated one physical core per physical server. This requires the Unity Connection VM Latency Sensitivity to be set to 'High' while at least one other VMs is set to 'Normal'. Recommend every VM to be set to 'Normal' except for Unity Connection VMs."
