Following the Linux 3.4 kernel benchmarks from last week, available now are the results from a three-way file-system comparison using the Linux 3.4 kernel as well as the Linux 3.2 and 3.3 kernels for reference. The three file-systems being pitted against each other are Btrfs, EXT4, and XFS.
The Linux 3.2/3.3/3.4 kernels were obtained from the Ubuntu mainline kernel repository and each file-system was tested with its default mount options and other system settings.
All benchmarking happened from an Intel Core i5 Sandy Bridge notebook with a 160GB Intel X-25 SSD. This Linux file-system/disk benchmarking was facilitated via the Phoronix Test Suite.
