Performance Efficiency Measure assesses characteristics that affect an application’s response behavior and use of resources under stated conditions (ISO/IEC 25010). Performance Efficiency affects customer satisfaction, workforce productivity, application scalability, response-time degradation, and inefficient use of processing or storage resources. The Performance Efficiency of an application lies in each individual component‘s performance, as well as in the effect of each component on the behavior of the chain of components comprising a transaction in which it participates.
