optimize CFLAGS from better performance #39
Description
I've noticed this library is built without any performance related compiler flags. Or at least it is not documented anywhere. It would be interesting to investigate performance gain from using eg:
CFLAGS="-Ofast -march=native -fuse-linker-plugin -flto-report -pipe" LDFLAGS="-O3 -flto" python setup.py build
for the source install.
Note: for binary distribution remove -march=native or replace it with some more generic CPU architecture.
I would have tested this, but I'm stuck at #38
