10-Way Linux File-System Comparison On Linux 3.10

When starting with the Flexible IO Tester, the first winner of our 10-way Linux file-system test on the Linux 3.10 kernel was actually Reiser4. The Reiser4 file-system with its tarnished history was actually noticeably faster than EXT4, XFS, and other mature Linux file-systems. ZFS also had a nice performance showing for being an out-of-tree solution. The slowest Linux file-systems for FIO were Btrfs and F2FS.

When turning to FS-Mark and its first test of running 1000 files of 1MB size, Samsung's F2FS (Flash-Friendly File-System) was out in front while ZFS was the slowest. EXT4 and Btrfs were in line with XFS and in the middle of the pack.

The results for FS-Mark were less spread in the multi-threaded test case with EXT4 and Btrfs and XFS all being front-runners while Reiser4, ReiserFS, and ZFS were the slower ones.
