From the developer:
ResourceWatcher enables you to see which applications are heavily using resources.
The program let you know exactly which programs are affecting your system, and by how much.
It sits in the status bar, and checks every once in a while to show you how much the application is using in terms of resources.
The program quickly ends programs you no longer want running and is highly customizable with filters.
