I&#x27;m a Python devotee, but I appreciate the anecdote.  I&#x27;m curious whether the switch 1) cost any features&#x2F;algorithms and 2) whether the anticipated performance improvement really panned out since the switch, or if the gain wound up being simply architecture&#x2F;deployment-related.  Stepping back, did the whole re-write really balance out with all the work that had to be done, or could you have stuck with Python and simply solved the problems at hand?
