"We tested out these five Linux file-systems with their default mount options using Ubuntu 10.04 LTS Alpha 1 with its Linux 2.6.32 kernel. Our test system this time around was an Intel Core i7 920 quad-core processor with Hyper Threading that was clocked at 3.60GHz, the ASRock X58 SuperComputer motherboard, 3GB of DDR3 system memory, a GeForce 9800GTX graphics card, and the file-systems were tested on a solid-state drive that was the OCZ Agility EX 60GB.

"Using the Phoronix Test Suite we ran the Dbench, IOzone, SQLite, PostMark, Threaded I/O Tester, Gzip, and FS-Mark test profiles. Besides the EXT4 change in the Linux 2.6.32 kernel, the Btrfs file-system in this most recent kernel release now has proper snapshot and sub-volume deletion support (along with the ability to rename snapshots and sub-volumes), discard support for SSD devices, and there are performance improvements too."
