Dispersion... still noisy after 108h

Hi I wanted to make a little dispersion test... I knew it would take a lot rendertimes... but that it's even not clear after 108h...

So SL 21.36 seems not to be enough for dispersion. Maxwell shows a time of 460h to reach SL25!!! And that for a res of 1024 x 768 (38,692 Triangles) :?

^^ why are the caustics so green?

The test before was a bit better sl 20.70 in 48h:

I used the same material in both scenes. ND 2,5; Abbe 35.

What does your lighting setup look like in the second test?

I believe this is one of the pictures we would like to see for the 1.2 advertisment... Not some chairs and teacups...
:( I hate when I see this render times...

maybe try the same scene with a cube or some other simple
geometry in the scene and see if there's any comparison with
the noise between the two objects. or the same object repeated
with material modifications applied to each to see if something
different occurs.
