The purpose of this thesis is to research effects of age on file system performance. For the testing purpose, two automated tests were implemented, which use open source benchmarks fs-drift and FIO to simulate aging and to measure performance. Research was aimed at effects of aging on popular Linux file systems XFS and ext4. Further research examined effects of underlying storage technology on performance of aged file systems. Implemented file system aging test was used to expand testing matrix of Red Hat Kernel Performance team.
