Great writeup. I have a ZFS account - how do those work under the hood? Is it a VM backed by a ZFS volume? How does the overhead compare to a normal account? I suppose using a VM eliminates some advantages of the special device.

If your account is enabled for zfs-send then it is a bhyve VM which has a zpool just for you (which is running on top of our zpool). I will have to look into this - does your zpool benefit from the metadata cache ? Perhaps not since it is a different zpool ...

  The metadata of the zvol on the host pool, does benefit from the metadata vdev (NOT A CACHE)

    OK, that is good to know - I will edit the post to reflect that (and also remove the poor use of the word 'cache').
