Jython vs Python3 vs Cython efficiency : <p>I see a lot of questions and answers related to python optimization but because python 3.x is advancing so rapidly, I am a bit confused as to which is the best option where. </p>

<p>I'm wondering if I'm misreading <a href="https://pybenchmarks.org/u64q/jython.php" rel="nofollow noreferrer">these benchmarks</a> which seem to suggest that the python3 interpreter outperforms jython and I'm wondering where and when alternative interpreters/compilers should and should not be used. </p>

<p>I have been running a lot of programs that are intense memory/cpu hogs and it's beginning to become more necessary to look at these tools especially with 3.6 being a lot greedier than 2.7 as far as I can tell.</p>
