I have described below the CPU parameters of ESXTOP command, In a virtual environment virtual-machine's mostly have performance issues as default even its small or enterprise but it's easy to find the reason "why" if we understand what exactly the performance parameters show's. There are several other parameter which needs to be considered for performance analysis and troubleshooting but these are by default which should be considered first level of investigation. %RUN:  This  value represents the percentage of absolute time the virtual machine was running on the system. If the virtual machine is unresponsive, %RUN may indicate that the guest operating system is busy conducting an operation. When %RUN is near zero and the virtual machine is unresponsive, it could mean that the virtual machine is idle, blocked on an operation, or is not scheduled due to resource contention. Look at other values (%WAIT, %RDY, and %CSTP) to identify resource co...
