As web applications become more complex, performance testing of these applications acquires greater significance and criticality. Performance is essentially determined by the load on the site at peak time under varying conditions. Typically, performance testing is conducted in a simulated environment using tools. However, performance as perceived by the user is most critical since the user is the ultimate judge for the success of the web site. Although the complexity of web sites makes it difficult to draw a common denominator for user perception and designer viewpoint, it is necessary to modulate user perceptions to aid robust web site design. This paper proposes a new model, PePPeR, which enforces incorporation of user perceptions in the design process. Using this model, the designer can consider the projected perceptions during performance testing without diluting application reliability. The model is substantiated through a detailed case study with empirical results.
