A dual chipset architecture, a method of operating a scheduler for a dual chipset architecture, and a computer program product for operating a scheduler for a dual chipset architecture. In an embodiment, the dual chipset architecture comprises a high performance processor, a low performance processor, and a scheduler for the processors. The scheduler is provided for determining an expected data traffic flow to the chipset, and for selectively enabling the high and low performance processors, based on this expected data flow, ahead of this expected data flow reaching the chipset. In one embodiment, a specified data traffic indicator is associated with the expected data traffic flow, and the scheduler uses this specified data traffic indicator to determine the expected data traffic flow. In an embodiment, this specified data traffic indicator is a value for a defined window size for the expected data flow.
