An administrator responsible for a VDl environment needs to investigate reports of slow logins.

According to the web search results, the two impacts on the cluster that will result from increasing the vCPU count on all of the VDI VMs are:

Increase CPU utilization%: CPU utilization is the percentage of time that a CPU is busy executing instructions5. By increasing the vCPU count on all of the VDI VMs, the administrator will increase the demand for CPU resources on the cluster, which will increase the CPU utilization percentage6.

Increase CPU ready%: CPU ready is the percentage of time that a vCPU is ready to run but is waiting for a physical CPU to become available5. By increasing the vCPU count on all of the VDI VMs, the administrator will increase the contention for physical CPU resources on the cluster, which will increase the CPU ready percentage6. A high CPU ready percentage can indicate performance issues such as latency or slowdowns5.
