Question

Quizplus · Accepted Answer

The virtual machine is experiencing application performance problems due to the fact that the virtual machine has the same number of CPUs as the host. Every time the application requests a multi thread to be processed, the host must have 4 available slots available to schedule. Recuing the virtual machine vCPU count to 2 would help.
