Initial Benchmark of Bcachefs vs. Btrfs vs. EXT4 vs. F2FS vs. XFS on Linux 6.11
A Phoronix benchmark compared Bcachefs with Btrfs, EXT4, F2FS, and XFS on an AMD EPYC server using PCIe 5.0 NVMe SSDs, showing Bcachefs improved stability. OpenZFS was excluded.

A recent benchmark conducted by Phoronix compared the performance of Bcachefs against other Linux file systems, including Btrfs, EXT4, F2FS, and XFS, using the Linux 6.11-rc2 kernel. The tests were performed on an AMD EPYC 8534P server equipped with Solidigm D7-PS1010 PCIe 5.0 NVMe SSDs, which are known for their high-speed performance. Each file system was freshly formatted and mounted with default options. The results indicated that Bcachefs has stabilized significantly in recent kernel releases, operating without errors during the tests. The other file systems also performed reliably, with no notable issues. However, OpenZFS was not included in this round of testing due to its lack of support for the Linux 6.11 and 6.10 kernels in released form. This benchmarking effort was prompted by requests from Phoronix readers for updated performance comparisons among these file systems.
- Bcachefs showed improved stability in recent kernel versions.
- The benchmark included Btrfs, EXT4, F2FS, and XFS alongside Bcachefs.
- Testing was conducted on high-performance Solidigm PCIe 5.0 NVMe SSDs.
- OpenZFS was excluded due to compatibility issues with the tested kernel versions.
- The tests were performed on an AMD EPYC 8534P server running Ubuntu 24.04 LTS.
