Performance evaluation of a multiuser interactive networking system – a comparison of modelling methods

Tadeusz Czachórski, Krzysztof Grochla, Adam Józefiok, Tomasz Nycz


The article presents a queueing model for performance evaluation of a large database system at an assurance company. Measurements were collected inside the working system to construct a synthetic model of applications activities. We apply simulation, Markov and diffusion models – their comparison, based on real data, may better verify the utility of particular methods than usual academic examples.
