Linux 3.4 Kernel File-Systems - XFS, Btrfs, EXT4

Benchmarks of the EXT4, Btrfs, XFS file-systems on an Intel SSD under Ubuntu 12.04 LTS x86_64. Benchmarking of the Btrfs/XFS/EXT4 file-systems with the Linux 3.2, Linux 3.3, and Linux 3.4 development kernels. Testing for a future article on Phoronix.

Compare your own system(s) to this result file with the Phoronix Test Suite by running the command: phoronix-test-suite benchmark 1206088-BY-1205299SU76
