Performance comparison of Docker and Podman container-based virtualization

The central topic of this paper is the performance comparison and potential issues of the container-based virtualization, with Docker and Podman as typical representatives. The measurements validity is managed with the use of the same testing environment, the identical hardware and software components. The testing procedure is conducted by the means of the Filebench, on CentOS Linux 7. The goal is to evaluate an impact of one and more container-based virtual machines on the file system performances. The obtained results are thoroughly explained and further presented in graphical form.
