Linux 3.14 Kernel File-System SSD Benchmarks
Written by Michael Larabel in Software on 25 February 2014. Page 3 of 3. 9 Comments

With four threads of 32MB writes, F2FS was delivering the fastest performance and the 3.14 kernel allowed it to recover from a regression in the Linux 3.13 kernel. EXT4 and Btrfs were rather unchanged.

When using the Threaded I/O Tester for doing random writes, EXT4 was now competing with F2FS.

The PostMark results varied quite a bit and showed EXT4 and Btrfs getting faster on the SSD with the Linux 3.14 kernel while F2FS regressed further in the Linux 3.14 kernel.

Overall, Samsung's Flash-Friendly File-System (F2FS) was generally the fastest Linux file-system tested on the SanDisk SSD inside the ASUS Zenbook Prime Intel ultrabook. When it comes to the Linux 3.14 kernel, the story isn't hugely different with regard to file-system performance: for some workloads there are some minor improvements for the three file-systems while in other workloads for F2FS there seemed to be some regressions. We'll see if these issues get fixed prior to the Linux 3.14 kernel. Have other Linux kernel benchmarking requests? Let us know!
