On it being slow, that may just be inevitable with the amount of calculations that happen in it - also in this case the user said they didn't care about speed, they just wanted the effect working :)
For nockain, I would start without any noise in the CoronaVolumeMtl, and adjust the settings until you get an evenly cloudy cube - volumetric effects are always scene scale dependent and you need to adjust absorption distance to get the desired result, which could be 1cm or 10cm or 1m depending on the size of the objects, scale of the scene, etc. (In my test scene, the cube is very large indeed, and this looks like a much smaller scale).
Once you have the "plain" version working, you could add some noise and distance map back in - again bearing in mind the scale of the noise will need to be matched to the scale of the scene, and the distances in the Distance Map will also need to match the scale of the scene. Hope this helps!
