Btrfs, EXT4, F2FS & XFS On Linux 7.2 vs. Linux 7.3 Performance
Earlier this week I showed off some of the very nice Btrfs performance gains on Linux 7.3. For those wondering what kernel optimizations may have carried over to other file-systems or other file-system specific enhancements, here are Linux 7.2 vs. 7.3 Git performance benchmarks across Btrfs, EXT4, F2FS, and XFS on the same system.
In a recent comparison of Linux kernel versions 7.2 and 7.3, performance benchmarks were conducted on four file-systems: Btrfs, EXT4, F2FS, and XFS. The system tested was a Sandisk SN8000S SDEPNRG-2T00-1006 2TB PCIe 4.0 x4 SSD, freshly formatted and mounted with default mount options. Both kernels were built identically, with only the differences lying in their respective versions.
The host operating system was Ubuntu 26.10 running on an HP Z4 G6i workstation powered by an Intel Xeon 678X processor. The only variable factor during the tests was the swap of kernels and file-systems. The results showed notable performance improvements in Btrfs on Linux 7.3 compared to Linux 7.2. It is unclear if these enhancements carried over to other file-systems like EXT4, F2FS, and XFS, or if they were specific to Btrfs.
Further investigation is required to determine the extent of performance gains in other file-systems when running Linux 7.3 versus Linux 7.2.
