When CPU frequency governor is set to 'powersave' mode, CPU is set to the lowest static frequency (within the borders of scalingminfreq and scalingmaxfreq). The 'scalinggovernor' feature enables setting a static frequency to the CPU.Frequency value must be between scalingminfreq and scalingmaxfreq. Currently, I am playing with recent Ubuntu Wily Werewolf on my personal notebook. This is a configuration guide to modify CPU performance.
