Now that kernel development activity is settling down for the Linux 3.15 kernel, here are some benchmarks of the EXT4, XFS, F2FS, and Btrfs file-systems compared to the stable Linux 3.14 kernel performance.
The benchmarks in this article are a Btrfs, F2FS, XFS, and EXT4 file-system comparison between the Linux 3.14 and 3.15 Git (as of 6 May) kernels when carrying out these disk workloads on a 240GB OCZ Vertex 3 solid-state drive.
