Host core CPU utilization is higher than expected for moderate workloads

Description

When GPU performance is being monitored, host core CPU utilization is higher than expected for moderate workloads. For example, host CPU utilization when only a small number of VMs are running is as high as when several times as many VMs are running.

Workaround

Disable monitoring of the following GPU performance statistics:

vGPU engine usage by applications across multiple vGPUs
Encoder session statistics
Frame buffer capture (FBC) session statistics
Statistics gathered by performance counters in guest VMs

Status
