As we have a total of 369 worlds (see Figure 2.1), it is called
group of worlds. These worlds can belong to a group of idle worlds, group of system worlds, group of helper worlds, or another group of worlds.
Understanding CPU statistics
I will explain the statistics found in Figure 2.1. The first line you can find in esxtop or vtop starts ...
