1. An article comprising a storage medium having associated data, wherein the data, when accessed, result in a machine performing: monitoring a plurality of applications, as they are initially executed, to generate a corresponding plurality of application performance requirements interfaces (“APRIs”); storing the plurality of APRIs in a non-volatile memory; retrieving one of the APRIs from the non-volatile memory; and re-executing one of the plurality of applications, corresponding to the retrieved APRI, while the machine is controlled to operate at a performance level in response to the retrieved APRI; wherein, in re-executing, the performance level comprises a minimum of idle cycles of the machine.
