Is is slow. I have to admit I haven't used it in awhile, but there should be settings to use the gpu render engine. If you have a decent video card (preferrably Nvidia) it should go a lot faster. However, if you need to use the cpu, it will go very slow. Emitters make it slower as well as reflective or glassy surfaces and the size.

The settings you gave above are what I would use, so you're ok there. You just need patience...hehe. It's the nature of the renderer. All unbiased render engines are slow if using the cpu.

On my quad core an image that high with emitters and all that metal could possibly take a couple days. You may go a bit quicker if you have other computers and make yourself a small render farm.
