Presentation Abstract

The objective of creating a work load model (WLM) is to make sure that a real-time scenario for the system or application under test (AUT) is created. Accurate predictions and results can be made about the performance of AUT or system when realistic work load models are simulated.

Consider an application, which is made ready to go-live in the next 2 months, but the application performance behavior with real-time and varying user load is not available. To study the application performance behavior prior to its actual go-live with real-time and varying user loads, a BETA version of the same application is made available to the end users with a provision to provide his/her valuable feedback by the end user pertaining to application’s responsiveness. All the logs and other related data pertaining to the application are monitored and examined closely and the results are obtained. Some varying patterns can be observed, due to application specific behavior at varying user loads. Work load modeling technique need to be used here, to arrive at an optimal throughput or user load with which the application can be subjected to a realistic user load. The performance tests carried out using this work load model will simulate the application performance behaviour as in production or after go-live.
