“%WAIT”
The percentage of time the world spent in wait state.
This %WAIT is the total wait time. I.e., the world is waiting for some VMKernel resource. This wait time includes
I/O wait time, idle time and among other resources. Idle time is presented as %IDLE.
“%RDY”
The percentage of time the world was ready to run.
A world in a run queue is waiting for CPU scheduler to let it run on a PCPU. %RDY accounts the percentage of
this time. So, it is always smaller than 100%.
+Q: How do I know CPU resource is under contention?+
+A: %RDY is a main indicator. But, it is not sufficient by itself.+
