This paper includes analysis of modern filesystems performance in multidisk storage space configuration. In performance testing only popular open source filesystem types were used in GNU/Linux operating system: BTRFS, EXT4, XFS. Base file operations were tested in various local multi-disk storage configurations using Logical Volume Manager, that differentiated due to disk number, allocation policy and block allocation unit. In multi-disk storage configurations managed by LVM many allocation policies were used like various RAID levels and thin provisioning. The obtained filesystem performance characteristics allow to choose parameters of multi-disk storage space configuration, which provides the best performance for file operations. Research result show also which filesystem type is the efficient in storage space configuration with locally connected disks.
