If you find something like that, shoot it out to me. I'd be interested in making sure if I need to set anything like that.

Yeah, but thought I read somewhere that CPU_COUNT should be manually set to the number of "real" (non-hyperthread) cores to prevent the instance from over-allocating resources (e.g. parallel query).
