Utilizing dual core tech?

I know Blender is wicked fast already, but is it possible to write Blender to use both cores to improve performance?
(it looks like multi-core processors are the future)

It already use multiple threads when rendering.

turning on threads indeeds improves the performance on my dual 2.7 g5 significantly. although it doesn’t seem to work with yafray despite the “processors” option in the yafray dialogue, but thats an issue for another forum :stuck_out_tongue:
