Might be worth arranging for this to be referenced as a useful resource in a future release of the FreeNAS User Guide possibly in the ZFS Primer section https://www.ixsystems.com/documentation/freenas/11.2/zfsprimer.html

I'll submit a ticket for the docs team to consider that, but first I want to get about a week of feedback and changes.

Great into material. Can we have one the cover some of the more interesting knobs and buttons? Perhaps covering how to calculate ARC RAM usage due to L2ARC?

I'm looking to keep this simple, so that limits the "interesting" bit. The ZFS book states that the rule of thumb is 25 MB of ARC for each 1 GB of L2ARC. It might be lower with large blocks, but stuff that uses large blocks tends to stream well from disk anyway, so it's not incredibly relevant.
