In terms of this thread, though, the advice in the setuptools docs is indeed out of date - the downside of making sys.path longer overwhelms the benefit of zipimporter loading content listings into memory, especially in Python 3, which also caches normal directory listings for sys.path entries since the switch to importlib in 3.3 (the caching avoided a slowdown when importing from local disks, and provided a dramatic speed *up* when importing from network file shares).
