Linux 6.17 file-system benchmarks include EXT4, Btrfs, F2FS, XFS, Bcachefs, and OpenZFS.
EXT4 has scalability improvements, and Bcachefs is now in a frozen state in the mainline kernel.
Testing was done on Ubuntu 25.10 with a Linux 6.17.0-4-generic kernel using a Crucial T705 1TB PCIe Gen5 NVMe SSD.
OpenZFS was included as Ubuntu 25.10 patched it to work with Linux 6.17.
Bcachefs was tested in its upstream state, with plans for DKMS out-of-tree modules to be evaluated later.
Each file-system was tested with default mount options across various benchmarks.
