As of Linux kernel version + 2.6.21, the kernel no longer has a fixed 1000Hz timer + tick. This will (in theory) give a huge power savings + because the CPU stays in low power mode for longer periods + of time during system idle. + + However... there are many things that can ruin the party, + both inside the kernel and in userspace. PowerTOP combines + various sources of information from the kernel into one + convenient screen so that you can see how well your system + is doing, and which components are the biggest problem. |
