One Line Summary
Discussion of Linux idle power management vs other OSes
Idle power consumption is the single most important metric of platform power management. It dictates how long the battery will last on a mobile device, it dictates how quiet a desktop can be, and it controls the the minimal server room electricity bill. Further, idle power is the baseline power to which all run-time power measurements are compared.
Here we examine the latest idle power measurements of Linux versions and competing operating systems on mobile, desktop, and server platforms. We illustrate areas where Linux is strong, and where Linux needs to improve.
