Abstract

There have been numerous analytic computer system performance models based on the operational-law, arrival, and queuing theories. In today's speedcentric IT business environment, their simplicity is useful in ensuring the agile performance and capacity prediction of the computer system for the IT business. The analytic model is supplemented by simulation models, however, because it oversimplifies the system and also poorly represents the dynamic nature of the actual system. A simple and agile computer performance simulation model, which can support fast decision making, is more desirable than an accurate yet slow model. In this paper, an analytic model suggested by Menasce is examined based on the measurement data obtained from a Web server, and its simulation model is suggested, using ARENA, to verify that it allows simple and agile performance analysis and prediction.
