Sounds like cspear's advice for the IC has made your render times more acceptible until SR1 is released. No surprise there really as with IC =100 there is no interpolation of the shading points being calculated. A couple of hours is much better for now than 14 plus with only a partially completed render.
I wouldn't worry too much about experimenting with the alternative render dialogue. If the IDL improvements are as good as bb is reporting then it's not worth the time experimenting.
