Of course, i tried using Photon mapping with self settings.
But when it took 5h and it was rendered 1/3 picture, I said rather try MLT.
It is true that even after 10 hours was in the image noise. But it can be reduce using Gimp.
Difference of render time I can confirm in Photon Mapping and MLT too.

I was about to suggest you something, but after have done some tests before that I give up. I added my observations in the Render Tips for Kerkythea. (link)
