Performance Analysis of Cluster-Based Web System Using the QPN Models

Response Time Analysis of Distributed Web Systems Using QPNs

“…Earlier [12,13] we set the parameters for the system experimentally. We verified [12] the influence of the individual layers on the system performance.…”

“…We verified [12] the influence of the individual layers on the system performance. The paper [13] focuses on the expansion of the model by increasing the number of elements in layers. The current model (5) has only a few parameters, but it is fully functional and can be scaled to larger systems.…”

“…The models have been used as a background for developing a programming tool which is able to map timed behavior of Queueing Nets by means of simulation. We developed [12,13] our individual method of modeling and analysis of DWS. The well-known software toolkits such as Queueing Petri net Modeling Environment (QPME) [3] can be naturally used for our models simulation and performance analysis.…”

Modeling Web Client and System Behavior

“…Furthermore, there are some mathematical models for predicting the performance of the Web system. Almost in all cases, the authors conducted experiments [5,16]. This is the second way for performance engineering.…”

“…Followingly, we implement this model using the QPME tool [3] and verify system performance. Earlier, we proposed a kind of potential application of this method to bigger structure consumer-to-business interactions [2,5].…”
