@stefano ZFS on Linux still not mature yet, and FreeBSD support ZFS out of the box, to the kernel level.
If ZFS had close integration with the Linux kernel, it would have much or less similar I/O performance, both are POSIX complaint systems after all.
@cuddle @stefano ZFS is beast in general.
When i tinkered with poudriere, i had big difference in compilation time ZFS vs UFS. Rust is known for long compilation, and i don't remember by how much, but compilation was definitely faster with ZFS.
FreeBSD have better support for ZFS, no doubt.
