F2FS File-System Shows Regressions On Linux 3.10
Written by Michael Larabel in Software on 13 May 2013. Page 3 of 3. 3 Comments

The IOzone read/write disk performance was largely unchanged on these mainline kernel releases where Samsung's F2FS is officially supported.

CompileBench with its initial create operation saw a slight rise in performance when moving from Linux 3.9 to 3.10-rc1 with this particular configuration.

Similar to the Dbench result, with the PostgreSQL database server there is a dramatic decline in performance of Samsung's F2FS file-system when running the Linux 3.10-rc1 kernel over Linux 3.9.

F2FS continues to be a promising file-system for flash devices and remains backed by Samsung, but with the Linux 3.10-rc1 kernel there's some noticeable workloads (e.g. Dbench, PostgreSQL, multi-threaded FS-Mark) where the Flash Friendly File-System is noticeably slower. Benchmarks of F2FS on Linux 3.10 compared to EXT4, XFS, and Btrfs are forthcoming as we see how these other common Linux file-systems compare to their preceding kernel releases.
