Cpu Affinity - Polycom RealPresence 800s Getting Started Manual

RealPresence Collaboration Server 800s/Virtual Edition Getting Started Guide
These numbers assume that hyperthreading is enabled in the physical server's BIOS. If
hyperthreading is disabled, the above numbers should be divided by approximately 2.
Do not over-allocate cores.

CPU Affinity

Specific CPUs should be assigned to the virtual machine to assure that they will be available during periods
of high usage.
Guidelines:
● CPU core 0 should not be allocated. Host operating system performance may be affected if this core
is assigned to the virtual machine.
● At least one other core should not be allocated, regardless of how many licenses are purchased.
● When possible, it is advised to allocate cores on one CPU. This will enhance performance by
reducing CPU-to-CPU communication times.
● If other virtual machines are run on the server, the MCU does not require that the other virtual
machines be allocated CPUs.
To set CPU affinity:
1 In the VMware vSphere Client, right-click on the deployed MCU and then click Edit Settings...
