Last week I provided a look at the EXT4 and XFS performance from Linux 6.12 LTS through Linux 7.0 in its current development form. As mentioned in that article and as requested by many Phoronix readers, benchmarks have since wrapped up looking at how the Btrfs copy-on-write file-system performance has evolved since that late 2024 period and all major Linux kernel releases past that Long Term Support version.
Ah bummer… I’m currently using XFS on my server because BTRFS’s performance is less than stellar, although I’d love to use it to have native compression
I have use cases for btrfs, xfs and zfs. Somehow ext4 feels legacy or for small systems like Raspberries or when the cloud-image provided is already ext4.
I use BTRFS for personal PCs because of the subvolume feature (since one year or so), ZFS for backup/archive when I need raid and encryption capability without hardware raid and for proxmox. XFS is for large storage servers where hardware raid is already established or very special cases when a lot of inodes are needed.
