CPU History is an application that graphs your current CPU usage history in the Dock icon, and optionally in a floating window. It’s a lightweight CPU monitor  and gives you a quick visual readout on how hard your processor is working. CPU History is small to download, uses very little CPU time, and has a more customizable Dock graph than Activity Monitor.You can customize graph update frequency, choose display colors, and change the bar width in the graph. An optional floating graph can be turned on as well. In timing tests, Activity Monitor (and its sister process, pmTool) used a combined 18-20% CPU on an iBook G4. CPU History 1.0 used 1.2-1.8% CPU to graph the same information. On a MacBook Pro, Activity Monitor and pmTool used a combined 2.9% CPU, while CPU History 1.1 used 0.1% CPU.
