[FONT=Helvetica][SIZE=+1][B]7. CPU Scaling Governors[/B][/SIZE][/FONT]
[FONT=Helvetica] CPU governors control exactly how the CPU scales between your “max” and “min” set frequencies. Most kernels have “ondemand” and “performance.” The availability[/FONT]
[LIST]
[*][B]ondemand – [/B]Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
[*][B]interactive – [/B]Available in newer kernels, and becoming the default scaling option in some official Android kernels. The interactive governor is functionally similar to the ondemand governor with an even greater focus on responsiveness.
[*][B]conservative –[/B] Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
[*][B]performance –[/B] Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
[*][B]powersave –[/B] Available in some kernels. It will keep the CPU running at the “min” set value at all times.
[*][B]userspace[/B] [B]– [/B]A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
[*][B]smartass[/B] [B]– [/B]Included in some custom kernels. The smartass governor effectively gives the phone an automatic Screen Off profile, keeping speeds at a minimum when the phone is idle.
