AppTimer is a great application that will run an executable a number of times and time how long it takes for the application to reach a state where user input is being accepted before exiting the application.
After each run of the application AppTimer will attempt to close the application in an automated fashion while logging the time measurements to a log file.
It's main use is in benchmarking an application's startup time.
