  No problem. It was an interesting question that made me curious too.

    Came across some more info that you might find interesting. If true, htop is ignoring the cache used by ZFS but accounting for everything else.

      Yes, ZFS cache has been contentious for exactly the reason you posted, but it is generally not a functional issue.

      ZFS will release cache under memory pressure, however nice values of virtualizing can potentially demand it sooner than ZFS can release it.

      There have been many changes to ZFS to improve this, but the legacy of “invisible cache” is still around.
