Why would previous versions of Python3 (e.g., 3.5, 3.6) not perform as well as 2.7? What about Python3 makes it slower? Is it a language design issue?

We’re in the process of migrating several keras/TensorFlow-based projects to 3.6, and I’m struggling to get my emacs environment setup to handle Python 2 and 3 code simultaneously.
