Benchmarks Of The Official KQ ZFS Linux Module

(Other stories by Michael Larabel)

"Last summer we delivered the news that a native ZFS file-system implementation for Linux was coming by an Indian company known as KQ Infotech where they leveraged the Lawrence Livermore National Laboratories ZFS Linux code, finished it off in some areas, and took care of the POSIX support. This ZFS Linux module was eventually released to a group of beta testers -- us included -- and we ran some ZFS Linux benchmarks back in November using the latest beta code. Since that point, however, KQ Infotech has made their ZFS Linux port publicly available and earlier this month they declared this work as stable via its general availability release. We have decided to benchmark this latest ZFS Linux code to see where the performance now stands against the EXT4, Btrfs, and XFS file-systems.

"KQ Infotech now hosts their source trees for their ZFS work publicly on this GitHub page with the ZFS kernel module, LZFS (the ZFS POSIX layer for Linux), SPL (the Solaris Porting Layer for Linux), and their miscellaneous scripts for building packages. Behind their registration wall on the KQ Infotech web-site you are able to download their official binaries that have compiled packages for Red Hat Enterprise Linux 6, Fedora 14, Ubuntu 10.04 LTS, and Ubuntu 10.10. The 64-bit versions of these Linux distributions are required as well as using specific kernel versions (2.6.32-71.el6, 2.6.35.10-74, and 2.6.35-22-server)."
