Testing ghpythonlibrary_parallel on node in code

I am looking for ghpythonlib.paralle for speed performance testing. Using native grasshopper components called within python. I tested the grasshopper proximity 2d component. It doesn’t give me an error but the result is bizarre. Furthermore, I understand that the native component of grasshopper is more performing than python.
Any advice on this?
