Testing Btrfs On The Linux 3.16 Kernel
When running my initial Linux 3.16 file-system tests on an SSD I had to skip over Btrfs due to initial problems with the experimental kernel code. Fortunately, Btrfs has been fixed-up in Linux 3.16 and can now serve for some benchmarking.
As F2FS, XFS, and EXT4 were already tested on a solid-state drive using Linux 3.16 Git, in this article I'm just testing Btrfs when using the Linux 3.15 stable kernel against the Linux 3.16 Git kernel from 2 July. This Btrfs testing happened from an ASUS UX32VDA Core i7 Ivy Bridge ultrabook with 128GB SanDisk SD5SF212 SSD. A daily snapshot of Ubuntu 14.10 was used for testing while the kernel snapshots were obtained from the Ubuntu Mainline Kernel PPA for easy reproducibility.
As usual, the stock Btrfs mount options were used under each kernel. All testing was handled by the Phoronix Test Suite. These file-system results are on the next page. Linux 3.16 in Btrfs brings many changes for those that missed the earlier article covering the 3.16 Btrfs pull request.
