Ubuntu 12.04 LTS - Benchmarking All The Linux File-Systems
The PostMark test failed to run successfully under all seven Linux file-systems being tested, but for those that did, Btrfs was noticeably faster than ReiserFS, JFS, and EXT3.
When running a single Dbench client, the ancient EXT2 was the fastest. However, EXT2 is not enforcing syncs with the results being too fast for what can be sustained from the speedy Intel SSD. JFS had also performed remarkably fast, but between the leading EXT4, Btrfs, and XFS file-systems, EXT4 was on top. EXT4 had about a 25% advantage over Btrfs and XFS.
When it came to running FS-Mark with 1000 files of 1MB size, the XFS and EXT4 numbers were close while Btrfs had fallen behind and was on par with EXT3 on the Linux 3.2-based distribution. ReiserFS was the slowest.
