The methods Performance:Process and
Process:getProcess can seem similar, but return different data.
Performance:Process returns all Instances of Process Object from the Performance Data Helper (PDH) library. Invoking
Performance:process without any arguments retrieves all Process instances in effect at that point in time. Invoking
Process:getProcess without any arguments returns all currently running processes from the
PSAPI.lib. This method only lists processes that have the right to access this library. Do not confuse these methods.
