ZFS behavior under limited resources
...e, metadata and all. The I/O reported is similar in the NONE and METADATA case (17 MB/S) while when set to ALL, I/O is 3 - 4 time less (4-5 MB/S).

- ::memstat reports that zfs grew from the original 430 MB to about 1.5 GB
Q: Does mdb memstat reporting include ARC?
Q:...
