[AstroPy] Python 3.6 appears to be faster than 2.7/3.4/3.5

[Geert Barentsen]

Dear All,

At yesterday's AAS Hack Day (cf. #hackaas on Twitter), I decided to compare
the performance of AstroPy between different versions of Python.  I thought
you may all be interested to see the results, which are shown here:

Bottom line: the newly-released Python 3.6 appears to triumph over previous
versions.

I used AstroPy's existing benchmarks located at
https://github.com/astropy/astropy-benchmarks, and so these results are
only really applicable to the limited set of features being benchmarked
there.  Another caveat is that I only ran the benchmarks on Linux.  It is
reasonable to expect the best performance from 3.6 however, given how much
effort has gone into performance improvements (e.g. CompactDict).

The script used to create the graph is here:

Best wishes,
Geert
