Reduce Linux power consumption - 3 part series

Reduce Linux power consumption, Part 1: The CPUfreq subsystem This three-part series is your starting point for tuning your system for power efficiency. In Part 1, get up to speed on the components and concepts you need to fine-tune a Linux-based System x server for power efficiency. Learn how to enable the Linux CPUfreq subsystem, get instruction on C and P states, and determine which of the five in-kernel governors you need to boost power efficiency on your system. 15 Sep 2009

Reduce Linux power consumption, Part 2: General and governor-specific settings This three-part series is your starting point for tuning your system for power efficiency. In Part 2, follow a step-by-step guide on the general settings of the Linux CPUfreq subsystem and get more details on the five in-kernel governors -- performance, powersave, userspace, ondemand, and conservative -- and their settings. 23 Sep 2009


Reduce Linux power consumption, Part 3: Tuning results This three-part series is your starting point for tuning your system for power efficiency. In Part 3, the author compares the performance of the five in-kernel governors in both tuned and untuned states to show you how to optimize a Linux-based System x server. 07 Oct 2009
