Benefit
HiperDispatch offers very little CPU savings benefit on machines configured with a relatively small number of CPUs. However, the feature does help quite a lot as the CPU count increases. IBM mainframe capacity tables (and thus its software pricing) are all based on the assumption that HiperDispatch is active.
The other benefit of HiperDispatch - "parking" logical CPUs so that the number of CPUs on which z/OS dispatches work more closely matches the LPAR's weight - is applicable to even small machine configurations. (The benefit of this is the reduction of the "short engine" effect, making system performance more responsive.

Famous quotes containing the word benefit:
“The laboring man and the trade-unionist, if I understand him, asks only equality before the law. Class legislation and unequal privilege, though expressly in his favor, will in the end work no benefit to him or to society.”
—William Howard Taft (1857–1930)
“Traditionally in American society, men have been trained for both competition and teamwork through sports, while women have been reared to merge their welfare with that of the family, with fewer opportunities for either independence or other team identifications, and fewer challenges to direct competition. In effect, women have been circumscribed within that unit where the benefit of one is most easily believed to be the benefit of all.”
—Mary Catherine Bateson (b. 1939)
“Henceforth may the neglected lover constantly read me, and may my troubles, once they are known, be of some benefit to him.”
—Propertius Sextus (c. 50–16 B.C.)
