    A process pool means extra copying of data around which incurs a huge cost and this is made worse by the tendency for parallel-processing-friendly workloads often consisting of large amounts of data.

      Yup, which is why you should try to limit the copying by designing your parallel processing algorithm around it. If you can’t, you would handle threading with a native library or something and scale vertical instead of horizontal. Or pick a different language if it’s a huge part of your app.

      But in a lot of cases, it’s reasonable to stick with Python and scale horizontally. That has value if you’re otherwise a Python shop.
