What's red and green and only uses 96k of disk space? CPU History. It's a lightweight CPU monitor that sits in the Dock on your Mac, and gives you a quick visual readout on how hard your processor is working. It's customizable, easy to read, and won't put a big drain on your system.So why not Activity Monitor? Well, if you're just going to use it as a display in the dock, it's using way more system resources than you need. Its Dock readout also isn't as customizable as the one in CPU History, which lets you set the update interval, the width of the bars in the CPU graph, and the size of the icon in the Dock. The latest version also shows separate graphs for multi-core processors. It doesn't really do much, but CPU History gets its very specific job done with minimal hassle.
