Prestanda- och skalbarhetsanalys av Navcite ProApps

This thesis carries out studies on the Navcite ProApps platform to identify where the potential bottlenecks are, and what factors the affect the system the most. The thesis objectives were to find out how to measure the performance, where to do it, how to set up tests and how to study the results. With two servers in the system where one holds applications and various software, and the other one the databases the biggest focus was put on the first. There was used various simulation tools to simulate user traffic, factorial design to set up the tests and ANOVA, regression analysis and Box-Cox transformations to analyse the results. What the study showed was that the application server is the one server that will run into the risk of slowing down the system first. Then by comparing some users using an application with an equal amount of images retrieved by the application, the number of users had the biggest impact on the application server.Validerat; 20160202 (global_studentproject_submitter
