Today I am exploring 4 well known filesystem for Linux, and putting each one to the test: Btrfs, ext4, ext4 w/o journaling, xfs and openzfs. All of them are being tested on hardware, running the latest versions in the Debian 11 repos. The benchmark test I am using is iozone 3.493 the latest version of the software. You can find my benchmark scripts on Gitlab. I am performing 13 tests which are included in iozone to simulate workloads of different types to see how well each filesystem performs.

This video is based around a question I received from one of my viewers (and because its been a year since I updated the benchmarks). However, the main reason is after watching last Saturdays Linux Saloon, where some folks were making recommendations to use a particular filesystem, and making claims for performance that were unsubstantiated. As an engineer claims without facts always make me suspicious. Oddly enough marketing sometimes uses that method of hyping a product beyond its capabilities. So I wanted to know the truth. How well does btrfs actually perform against the older filesystems in linux?

Hope you enjoy the video as much as I did making it.
