This document demonstrates practical implementation of threading and multiprocessing in Python to optimize image processing performance. It walks through converting a sequential thumbnail generation script to use ThreadPoolExecutor and ProcessPoolExecutor, comparing their performance characteristics and explaining the differences caused by Python's Global Interpreter Lock.
