Filesystems performance in GNU/Linux multi-disk data storage

Smoliński M.

Journal of Applied Computer Science

2014

Vol. 22, nr 2

65--80

This paper introduces research results of I/O performance for modern filesystems configured on multi-disk storage configuration in GNU/Linux operating system. Filesystem performance tests include basic file operations statistics depending on local disks management software RAID or logical volume manager LVM. The results allow to choose the appropriate filesystem to data storage space configuration in GNU/Linux, that provides bests performance.

Modern filesystem performance in local multi-disk storage space configuration

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.
