multithreading with python

Hello world...

Can anybody offer some advice regarding multithreading and using GH components with python? I read Steve Baer's post (here) and tested a few commands myself, *but* everything is slower when using the parallel function. And the interesting thing is that it gets slower with every run. As you can see in the attached screenshots - the first run takes a few seconds as compared to the native GH component which finishes in 224ms. After multiple runs the python component is taking 3.9 minutes to run while the native component is finishing within a millisecond of the original time. What gives? I'm running this on a PC with 8 cores.
