(I have some difficulties with the interface here, no way to edit inside the frame)
Observe the following increase of execution times. In first sage interactive session I execute from D=0 to D=9. Then I quit, relaunch sage, loads my module, and execute from D=9 down to D=0. The executed procedure returns a value, apart from that it is not supposed to alter memory or anything else. It uses auxiliaries declared with @parallel.
This is on a quite recent macOS.

And now in reverse in a new Sage interactive session
