Apmiser is a daemon that monitors the CPU usage patterns of your laptop and automatically switches between power-saving mode (in which the CPU is underclocked) and normal mode, depending on whether it thinks you will need the extra CPU speed. This lets you leave your laptop in it's power-saving state without having to suffer from poor performance when you need to perform a CPU-intensive task. Apmiser currently only supports IBM Thinkpads via tpctl, but support can be easily added for any laptop that supports switching power-saving modes programmatically.
