Dec 31, 2010 · The main benefit of x86-64 for a lot of cases is that it's typically ~10% faster than the same code compiled for 32bit. Of course it's great if you have a use for large amounts of memory, or 64bit integers. (Or arbitrary-precision integers like Python uses) – Peter Cordes. Jun 10, 2016 at 3:01.

- Compilers Installation and Configuration
Each Python version uses a specific compiler version (e.g. CPython 2.7 uses Visual C++ 9.0, CPython 3.3 uses Visual C++ 10.0, etc). So, you need to install the compiler version that corresponds to your Python version :
If the package's setup.py (still) uses distutils rather than the recommended setuptools, you may need extra steps: 1. distutils only supports the very minimum of compiler setups. The sections in this guide corresponding to them explicitly mention distutils. 2. For other setups, you need to run the compilation from the "SDK prompt" of the correspond...
Compatible architectures are specified for each compiler in brackets. Before do anything, install or upgrade the SetuptoolsPython package. It contain compatibility improvements and add automatic use of compilers:
