Abstract

This paper addresses aspects of performance overhead when using paravirtualization techniques. To quantify the overhead the paper introduces and utilizes a new testing method, called the Zachmann test, to determine the performance overhead in a paravirtualized environment. The Zachmann test is used to perform CPU and memory intensive operations in a testing environment consisting of an exemplary Enterprise Resource Planning (ERP) system and a Xen hypervisor derivate. We focus on two issues: first, the performance overhead in general and second, the analysis of "overcommitment" situations. Our measurements show that the ERP system's performance suffers up to 44% loss in virtualized environments compared to non-virtualized environments. Extreme overcommitment situations can lead to an overall performance loss up to 10%. This work shows the first results from a quantitative analysis.
