    I leave mine set to Performance all the time. OnDemand has a noticeable impact on system responsiveness. As measured by a Kill-A-Watt meter at the power outlet, there is zero difference in power savings between OnDemand and Performance, while the machine is idle. When the machine is not idle, I don't care about power consumption, I want max performance and max responsiveness.

    This is for a desktop machine BTW. Laptops are different, and even fractions of a watt add up to less heat and more battery time in a laptop, so maybe these other governors have some value in the laptop world.
