I change this, and just WOW what a difference!!!
Settings in TWO places:

✦ 04 Change the Tile Size
(Rendering with 128 samples)

64: 13.38 (Default)  
128: 9.04 
256: 7.98 (Adopted)
512: 8.29

Retest with "New" file:

✦ 09 Clamp it

✦ 10 Turn Off Caustics

On: 7.95

✦ 11 Object Instancing
Instead of Shift-D to duplicate, Alt-D to share data (if they are going to be identical)

✦ 12 Adaptive Subdivision
Per video, it's in the 'Subdivision Surface' modifier of an object (if you add it),
but the option doesn't appear in mine. Sooo…

✦ 13 Remove Alpha Transparency
Use for things you have a lot of, such as leaves on a tree.

✦ 14 Reduce the Strand Count
Use of things like carpet, hair, etc.
