Running Time of Application

The application has a feature called running time. It is one of the parameters for measuring its performance. It is written in a particular language and is designed to perform a specific task. Applications run in a specific environment. The execution of the business will depend on the application’s running time. It must be optimized in order to get the maximum benefits out of the application.
