EXT3 vs EXT4 vs XFS vs BTRFS filesystem comparison on Fedora 18
As always, we want to check the current state and performance of Linux filesystems. This time is the turn of Fedora 18 x86_64, with kernel version 3.9.4-200.
The benchmarked filesystems are:
- ext3, the classic Linux filesystem
- ext4, the latest of the ext-based filesystem and the default choice for many Linux distribution
- xfs, an high performance filesystem designed with scalability in mind
- btrfs, the new, actively developed, feature-rich filesystem
Note that this article has a focus on performance. For an in-depth, feature-based comparison, you can see the relative Wikipedia page.
