File System Performance Comparison With the Hypervisors Esxi and Xen

Abstract:
This paper contains a file system performance comparison among type-1 Linux-based hypervisors, with ESXi and Xen chosen as representative examples of such hypervisors. At first glance, both hypervisors may seem to share a similar Linux-based architecture, but upon deeper examination, notable differences emerge. We have used a benchmark called Filebench for experimental measures of file system performance. Filebench is chosen because of its high level of flexibility and adaptability, which enable the emulation of real applications in typical server environments. This paper comprises a mathematical model of the type-1 hypervisor environment, followed by a real file system experiment that serves as a specific case study. The model is employed to interpret the file system performance results obtained from the experimental measures. The guest operating system utilized in our experiments was CentOS 9, selected as a typical representative of Linux distributions. We conducted experimental tests with one, two, and three virtual machines operating simultaneously
