Benchmarks Of The Official KQ ZFS Linux Module
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.
For running todays tests, Ubuntu 10.10 was used with its Linux 2.6.35 server kernel as to use KQ Infotech's official ZFS Linux packages. The ZFS Linux performance was then compared to that of EXT4, Btrfs, and XFS using the Linux 2.6.37 kernel to represent the latest stable look at those file-systems' performance.
