That was some good advice, thanks. I Reduced the diffuse samples to 4,
diffuse rays to 3 but had to increase AA to 20 to get an acceptable
amount of noise. The quality is about the same as before but the render
time was reduced to 1h:33minutes. Also got rid of the sampling errors by
clamping the sampling values.
But still much more fine noise overall then the Octane render, so I'm
rendering one with a diffuse sample setting of 6.

So far Octane is still the winner by a landslide. It's very quiet all of
a sudden, Maxwell, Vray anyone ?!

When using high AA samples (which is necessary for DOF or motion blur)
I believe you can pretty much keep diffuse samples down to 1 or 2. You
have to oversample a lot for the DOF, and this AA oversampling takes
care of diffuse areas as well. Also, for this scene with the large
windows you may get away with 2 or 3 bounces.

I'm rendering on a 6 core i7 3930 overclocked to 4 Ghz, so Arnold
is using 12 threads. With AA set lower the DOF is very noisy. But
you're right, maybe I could lower the diffuse samples a little.
