EXT4 vs. XFS vs. Btrfs HDD Benchmarks On Linux 3.15

Btrfs was edging ahead of XFS and Btrfs with the IOzone write test although the performance on the Linux 3.15 kernel was unchanged compared to Linux 3.14 stable.

Btrfs remained in the lead, this time when running Threaded I/O Tester's random write test with four 32MB threads.

With the PostMark disk benchmark, XFS and Btrfs were slightly faster with the Linux 3.15 kernel over Linux 3.14, although the EXT4 performance was rather unchanged.

Overall there wasn't too much to see out of these test results comparing the 3.14 and 3.15 file-system performance with XFS, Btrfs, and EXT4 on a Western Digital VelociRaptor hard drive. The overall winner though for the best performance from the HDD-based system appeared to be Btrfs but XFS also performed strongly against EXT4.
