SSS Render Speed Diffuse vs Specular Tweet

[Witpapier]

Paul can you maybe tell me if there is a speed difference between using Diffuse SSS or Specular SSS

[face_off]

Diffuse SSS was about 15% quicker for me than Specular SSS on the head test scene I use. I can't get which the same quality with specular as I get with diffuse, because there is slightly less light coming out of the material (since the specular transparency is 0).
