Btrfs Is Not Yet The Performance King

"While we have talked about the Btrfs file-system before, as a quick primer it was originally developed by Chris Mason at Oracle and was merged into the mainline kernel with Linux 2.6.29. Though present in the mainline kernel, the Btrfs file-system is still undergoing heavy development and its disk format has yet to be finalized. The Btrfs file-system supports writable snapshots, sub-volumes, object-level mirroring and stripping, data checksums, compression, online file-system checking support, and online defragmentation support. With solid-state drives also becoming increasingly common, there is also a SSD-optimized mode for Btrfs that should increase performance. Btrfs is considered a technological step-up from the EXT4 file-system and a competitor to Sun's ZFS file-system, which soon may actually be owned by Oracle.

"For our Btrfs benchmarking we used an Intel Core i7 processor running at 3.60GHz, an ASRock X58 SuperComputer motherboard, 3GB of DDR3 memory, a NVIDIA GeForce 9800GTX graphics card, and a Seagate ST3320620AS SATA 2.0 hard drive. On the software side was Fedora 11 Preview with the Linux 2.6.29 kernel, GNOME 2.26.1, X Server 1.6.1, xf86-video-nouveau 0.0.10, Mesa 7.5, and GCC 4.4.0.

"When benchmarking XFS, EXT3, EXT4, and Btrfs each time we did a clean DVD installation with a 200MB /boot partition formatted to EXT3, a 4.9GB SWAP partition, and the / partition occupied the remainder of the 320GB Serial ATA 2.0 disk and was formatted to the file-system being tested at the time. For those looking to try out the Btrfs file-system in Fedora, the icantbelieveitsnotbtr option needs to be passed to Anaconda at boot-time followed by manually partitioning the drive."
