Linux 3.15 SSD File-System Benchmarks

While running AIO-Stress on the Vertex 3 SSD seemed to be getting into some system memory caching, the EXT4 and F2FS file-systems reported improved results with the Linux 3.15 kernel over Linux 3.14. Meanwhile, Btrfs and XFS were slightly lower with their readings compared to Linux 3.14.

With Dbench there wasn't too much to see but F2FS from Samsung was the fastest. However, Samsung's Flash-Friendly File-System reported slightly too fast results than what would be expected of Serial ATA 3.0 solid-state drives, so compared to the other file-systems may be waiting to commit some data to the disk.

With the random write Threaded I/O Tester performance the F2FS performance seems to seem degraded with the Linux 3.15 kernel compared to Linux 3.14 stable; the other file-systems appeared unaffected.

With the PostMark mail server disk benchmark, the F2FS file-system edged past XFS for being the fastest.

For those curious about the file-system changes made with Linux 3.15, see our many Linux 3.15 articles covering the merge differences. There's also other benchmarks hosted on Similar benchmarks from a hard drive system are coming shortly.
