Btrfs / EXT4 / F2FS / XFS Benchmarks On The Linux 4.12 Kernel
Written by Michael Larabel in Storage on 20 May 2017. Page 2 of 2. 24 Comments

With the SQLite benchmark, there isn't much change in performance with 4.12 and Btrfs' default CoW behavior makes it much slower than the others. XFS continues to have a slight advantage in this test when using the default mount parameters over EXT4 and F2FS.

With BlogBench we see that the Flash-Friendly File-System is seeing better performance out of the Linux 4.12 kernel while the other file-systems remain unchanged. For BlogBench, XFS is the slowest while EXT4 is the fastest but F2FS has now secured a second-place victory with the 4.12 improvements.

EXT4 is the fastest for Compile Bench with Linux 4.12 followed by F2FS, XFS, and then Btrfs in a distant last place.

With the PostgreSQL benchmark, XFS saw a performance regression from 4.11 to 4.12, now losing its first place finish to EXT4. EXT4 saw a small performance boost out of Linux 4.12 to help it secure its first place victory in this database test. The F2FS and Btrfs results were largely unchanged.

Those wishing to dig deeper into this latest Linux 4.12 file-system benchmarking data can see this result file. More tests including fresh SSD RAID numbers, more I/O scheduler comparisons, and even some fresh HDD benchmark numbers will be available on Phoronix soon.
