This tool can be included in a package, and then run using a script loop to test out the stability of the App-V client.  It is also a very interesting test app for Perceived Performance in that it generates almost no system load while being very sensitive to jitter delays in CPU thread scheduling caused by other things.

Consists of just an exe. Run with /? parameter in a cmd prompt for syntax.

The application starts by displaying a simple Win32-based gui dialog.  It wakes up on a short timer and updates the display, and when the long timer expires the app shuts down automatically.  Using lots of very short timers allows the app to be affected by other running apps when the timer expires.  Comparing elapsed runtimes of the overall app execution allows for relative measurements to be made about how system performance is affecting user perceived performance.
