A couple of possibilities for avoiding that - one method could be that I would only do the boolean calculation just at the very end after you have picked the extrude distance, instead of trying to do it on every mousemove.

But it also may be possible for me to make a special case faster boolean for just this one particular purpose since it will be for curves that are sitting on a plane of the object, rather than for a fully general surface/surface intersection that the booleans normally calculate.
