I believe that, overall, Python 3 is still slightly slower than Python 2,
but it's a near thing. Have a look at the latest performance benchmarks:

Eyeballing the graph, I estimate that the latest 3.x version is probably
about 10% slower overall, although different benchmarks show different
speeds.
