    BT tested this when it was back in beta status.

    Basically, HPSPO is a kind of halfway between no protection, and the old full-on storage protection.
    You split up your storage pools so that no pool has both user and system storage. User storage is then put into a different
    MVS storage key, so that if a user program tries to overwrite system-owned storage it will fail. HPSPO won't stop
    a task overwriting another task's storage.

    As far as performance goes, the overhead of having HPSPO on is negligible.
