This is 250 times faster. The difference is of course that with
Hob3l, the result is sliced into layers, as the following image

The difference of the conversion technique is visible in the model
view of the STL, where the 2D CSG slicing technique clearly shows the

The final result of the slicer, however, is indistinguishable (I was
unable to replicate the exact same view, so the Moiré patterns are
different -- but the result is really the same):
