--- Comment #1 from Graham Perrin <grahamperrin@freebsd.org> ---
I don't know about ZFS in 12.4-RELEASE.
----
For OpenZFS in 13.0-RELEASE and greater, take care to not confuse these two:
vfs.zfs.arc.meta_limit_percent: 75
vfs.zfs.arc.meta_limit: 0
fs@ please, can you advise?

Is Linux still exceptional?
