I created issue 22486 about the gcd() performance. I think we can close this ticket - I don't see any more obvious low hanging fruit and future findings can have their own ticket. Out of interest, I modified the fractions module to compile Fraction into an extension type with Cython. For the benchmark, it currently gives me a 10x speedup over the original fractions module in Py3.4. I uploaded my initial attempt to PyPI and it's on github: https://pypi.python.org/pypi/quicktions https://github.com/scoder/quicktions That makes a C implementation of Fraction generally worth considering for CPython.
