Ultimate Comparison: Bcachefs, Btrfs, EXT4, F2FS, and XFS File System Performance on Linux 6.15

Bcachefs is gaining attention as its file-system is nearing the removal of the “EXPERIMENTAL” label. Many readers have been curious about how it performs compared to other file-systems. Today, I’ll share some new benchmarks comparing Bcachefs with Btrfs, EXT4, F2FS, and XFS using the Linux 6.15 kernel.

All tests were conducted on a fast 2TB Crucial T705 PCIe 5.0 NVMe SSD, known for its speed and reliability. This makes it a great choice for Linux users wanting top performance. Each file-system was freshly formatted with default settings, ensuring a fair comparison.

Benchmarking different file-systems helps us understand how each performs under common workloads. The results can influence decisions for developers and power users looking to optimize their systems.

It’s worth noting that according to a recent survey from the Linux Foundation, user adoption of different file-systems varies greatly. For example, while EXT4 is still quite popular, newer options like Btrfs and Bcachefs are slowly making their mark. This growing interest might be due to their advanced features, such as snapshots and built-in checksumming.

As Bcachefs continues to develop, it could become a preferred choice for many. Benchmarks like these are crucial as they provide insight into real-world performance. Additionally, expert opinions suggest that as storage demands increase, robust file-systems like Bcachefs will be essential for efficient data management.

Understanding these insights can make a difference for those looking to choose the right file-system for their needs. With performance data at hand, users can feel more confident about their choices. For further details on these benchmarks, check the full analysis on Phoronix.
