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.
