The fundamental reason that we started on this track is the need to get off of Python 2, which has reached EOL and from which the community is moving away. Because of APIs we're using and such, it's not easy to switch to Python 3. Because of API changes in GAE, moving to PyPy on Flex is also still difficult and doesn't solve the problem of still being on Python 2. Performance is one of several important reasons for the move to Go, and not the top reason.
