It probably depends on the use case but there has been considerable optimisation work done in recent Python versions (the web pages you cited mostly talk about Python 3.4, which from an optimisataion POV is ancient history). There will be even more improvement in the future but we're now at a point where a fear of performance regressions compared to Python 2.7 shouldn't keep one from moving to Python 3.6 or 3.7.
