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.
Remember that different usage patterns can favor different filesystems, so I don't pretend to elect the best, stronger filesystem on earth. I simply want to help you in the choice of a good filesystem for your workload.
