Appriority is an easy-to-use tool for Mac OS X that simply makes the app you're working in go faster by allowing you to optimize the CPU load on your computer. Once fully configured, Appriority works by suspending and resuming applications as you switch among them. Inactive applications can be set for suspension which will eliminate their CPU usage until you switch back to them. The benefits of this are improved performance in the application you currently have active, less battery power used while mobile, and less heat produced by your computer.
