A Web Server Performance Analysis Based on Queuing Models -Course Project for IK1611 (Dimensioning of Communication Systems)

This paper presents a detailed web server performance analysis for a company whose website has performance problems – their customers have been experiencing long response times and high rejection rates. In order to analyze and solve the problem, two queuing models are suggested: M/M/1/L and IPP/M/1/L. Relevant parameters for both queuing models are estimated, and a simulation for each model is performed with the corresponding parameters having been estimated. Comparing the results to reality, IPP/M/1/L is more suitable for modelling the web server. In the end of the paper, a suggestion on how to lower the response time and the rejection rate is proposed.
