With the copy-on-write Bcachefs file-system considering its on-disk format now “soft frozen” and nearing the point of potentially removing the “EXPERIMENTAL” flag on it, a number of Phoronix readers have been requesting some fresh benchmarks of this open-source file-system. For your viewing pleasure today are some fresh benchmarks of Bcachefs and other file-systems atop the Linux 6.15 kernel being released as stable later this month. On the benchmarking block today are Bcachefs, Btrfs, EXT4, F2FS, and XFS in-tree file-systems.
Bcache, Btrfs, EXT4, F2FS, and XFS were all freshly tested off the Linux 6.15 Git kernel of the time of testing. Each file-system was freshly formatted and running with its default mount options.
All of the file-system benchmarks were carried out on a 2TB Crucial T705 PCIe 5.0 NVMe SSD. The Crucial T705 is one of the fastest consumer solid-state drives at the moment and an interesting candidate for Linux enthusiasts and power users.
A variety of storage-related benchmarks were then carried out atop this Linux 6.15 powered desktop for seeing how Bcachefs is competing with other Linux file-systems out-of-the-box on this latest kernel version.
