Is the compositor multithreaded?

In my tests with the compositor, I’ve noticed my 4-core OSX machine go from 400% rendering in the activity monitor during the normal render, down to 100% during the compositing phase?

Is the compositor multithreaded? If so, how can I enable it?

If it’s not multithreaded, is that on the list for 2.5? :slight_smile:

Sorry if this has been covered in previous posts. I did a search and couldn’t really find a definitive answer.

iirc only the compositor in 2.5 is multithreaded…
