Also in that thread was the following advice. I had seen a Blender Guru Video on 18 ways to speed up Cycles.

18 ways to Speed up Cycles

I did watch it though, and once again remember that these apply mainly to Cycles, but Superfly can probably benefit as well. You'll notice that I only specifically posted 12 suggestions. That was because a few of them were Cycles specific, like using the new Denoiser filter, using Portals, or using the latest version of Blender.

reduce light Bounces

Use GPU

Change the Tile Size (Smaller for CPU) (Larger for GPU)

Reduce Samples

Use newest version

Use a different OS

Clamp it. The higher the better. Indirect only.

Turn off Caustics

Remove Alpha transparency.

Reduce the strand count (Hair & particles)

Remove Volumetrics

Cut Subsurface Scattering (If you don't need it)
