This requires scoping first!!! Opened this issue just to start the discussion.
Conversion of very heavy models is always going to be "slow", but in Rhino specifically, where BREPs are the most common geometry you'll find, we could do some improvements in the conversion side to speed up the process:
Look into multithreading conversion for each object in a layer (similar to how GH does one conversion per object in a task).
