FreeCAD and quadcore

Post by kwhh.st »

Hello,
I have a basic questiion :? :
Because freecad is quiet slow during complex operation I would like do know how to speed up the program. Does it use all cpu of a quadcoe computer?
Thanks
Kurt

Kurt,

no it´s mostly single threaded , as far as i know due to limitations of the underlying code. Search the Forum for multihreading to find posts around that..

Not at all, BOPs are paralleled. They are the slowest thing, usually. So it does help to have multicore cpu. I have no idea how much gain does it give. There was a thread where it was being tested...

BOP = Boolean OPeration, it's the acronym used internally in Open Cascade (OCC).
