> Is it possible to multi-core the boolean calculations as well?

It's theoretically possible... But difficult in practice unfortunately. It would require quite a few changes to the geometry library code, which creates a big problem for maitenance such as applying bug fixes or other updates from the core library.

I don't have that problem with the mesher since that part is all my own code.


There are also going to be some other big speed optimizations in the next beta for the dynamic feedback during transforms, like when you are moving the mouse around when dragging or mirroring objects, etc... This should also help out quite a lot when working on a heavy model.


You probably already know this, but just in case the other thing that can currently help a lot with heavier files is to go to Options / View / Meshing parameters, and set "Mesh angle" to something like 20 degrees, and uncheck "Add detail to inflections". That produces a much less dense display mesh which won't look quite as nice on the screen but it will conserve a whole bunch of memory and reduce display mesh calculation time.

The next beta will not quite have the display mesher working on multiple cores yet, only the file export mesher at first. But it won't take too much to get multi core going for the display meshing as well in a bit.
