From a system with very little activity, nothing happening, no disk, no cpu, I have a very high WAIT time.


      ID      GID NAME             NWLD   %USED    %RUN    %SYS   %WAIT %VMWAIT    %RDY   %IDLE  %OVRLP

* “%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.

Q: Why do I always see a high %WAIT for VMX worlds?
A: This is normal. That means there are not too much activities on them.

So in your example RHEL2, is not doing very much. At Rest or IDLE.
