ZFS Still Trying To Compete With EXT4 & Btrfs On Linux

With the recent release of ZFS On Linux 0.6.2 that provides an open-source native Linux kernel module implementation of the Sun/Oracle ZFS file-system, the performance is faster, there are greater Linux kernel compatibility, and other improvements. Here's a fresh round of ZFS Linux benchmarks against EXT4 and Btrfs.

With the recent release of ZFS On Linux 0.6.2 (read the already-linked article for more details), the file-system was benchmarked against the mainline EXT4 and Btrfs file-systems. This latest round of Linux file-system testing happened from the System76 Gazelle Professional with Intel Core i7 4900MQ "Haswell" processor and high-end Intel 510 120GB SSD (SSDSC2CW12). This single solid-state drive was tested under all three file-systems with stock mount options for each of the file-systems to perform a fair and "out of the box" comparison. Older releases of ZFSOnLinux couldn't be tested since only with the new release is there Linux 3.10/3.11 kernel support and the latest Linux kernel release was desired for also offering the latest comparison to EXT4/Btrfs.

All of the file-system tests were conducted using the Phoronix Test Suite professional automated testing platform and enterprise-ready OpenBenchmarking.org.

These tests today provide a clean look at the ZFS / Btrfs / EXT4 performance on the Linux 3.11 kernel in a stock single SSD configuration from an Intel Core i7 system. Workstation tests from multi-drive configurations may come pending interest from Phoronix Premium subscribers.
