Add warning to autotune tooltip
Seen various posts in the forum recently regarding the autotune feature in FreeNAS. Majority of the time, an uninformed user of FreeNAS enables this feature believing it to be a magical option to fine tune their system for optimal performance. In reality, it does nothing but cause headaches for the end user, usually resulting in poor performance. Please can the autotune feature be hidden, or at least a HUGE RED WARNING informing the end user this may degrade performance?
Just a couple of examples (old and new forum posts) where it's impacted performance:

Currently the docs say: FreeNAS® provides an autotune script which optimizes the system depending on the installed hardware. For example, if a ZFS volume exists on a system with limited RAM, the autotune script automatically adjusts some ZFS sysctl values in an attempt to minimize ZFS memory starvation issues. It should only be used as a temporary measure on a system that hangs until the underlying hardware issue is addressed by adding more RAM. Autotune will always slow such a system, as it caps the ARC.
What else would we want to say?
