Performance comparison of selected virtualization platforms

The suitability assessment of implemented virtual platform must precede the implementation itself. The aim of the article is to experimentally assess the performance of freely available virtualization tools in several aspects. In the process of virtualization of any environment the performance decreases regarding a host system because of an application of isolating technologies. The performance parameters of CPU, inquired in two different tests, speed of retrieving and writing on a virtualized hard disc and also speed of response of a virtual network interface were chosen for comparison. The aim of the article is also to present the results of testing and chosen tested tools together with used methodology. The measured values are presented in graphs and accompanied by their interpretations. On the grounds of measured values one of the tested virtualization tools is recommended, which measured values shown the best characteristics.
