HDD & SSD File-System Benchmarks On Linux 3.9 Kernel
For those curious where the common Linux file-systems stand performance-wise for the Linux 3.9 kernel, here are benchmarks from a solid-state drive and hard drive when comparing the EXT4, Btrfs, XFS, and F2FS file-systems from this yet-to-be-released Linux kernel.
In terms of the changes over Linux 3.8 for the different file-systems, here's a summary of the changes while clicking the links will reveal more details.
EXT4 File-System Updated For Linux 3.9 - There's hole punching support for non-extent-mapped files plus other updates.
Linux 3.9 Gets Btrfs RAID 5/6, Fsync Performance - The Btrfs file-system now has experimental support for RAID 5 and RAID 6 plus fsync performance enhancements and other work.
XFS On Linux 3.9 Takes Care Of Open Issues - The widely used XFS file-system has received various minor bug-fixes and updates with Linux 3.9.
Samsung Brings Fixes To F2FS In Linux 3.9 Kernel - This is the new "Flash Friendly File-System" introduced by Samsung in the Linux 3.8 kernel and has already shown very promising performance results for USB flash drives, SDHC storage, SSDs, and other scenarios as tested on Phoronix.
The disk drives for which the file-systems were tested was a 60GB OCZ Solid 2 SSD and a Western Digital RE4 1TB SATA Enterprise HDD. All of the file-systems were tested with their stock mount options from a Linux 3.9 kernel Git snapshot. For the F2FS file-system, it could only be tested on the solid-state drive since it isn't supported by traditional rotating hard drives. All testing happened from an AMD FX-8150 Bulldozer system running Ubuntu 13.04.
Let's see the results now for this four-way file-system shootout on a HDD and SSD...
