Thanks for the great info on this blog, I find it very helpful. Regarding hyperthreading, when I kick a scene file it will use all 12 threads (intel xeon X5650) but it doesn’t go above 70% during the render. I’m still trying to figure it out and I have a few more tests to do but I thought I’d mention it.

  Apologies, I mean it doesn’t go above 70% CPU usage. I think I was a bit vague in the first post.

  I guess I would look at what’s in the scenes. If every scene did that, that would be odd.
