Issue 995023: Should build Python dylib with -single_module (original) (raw)

According to bbum, dylibs built with -single_module load significantly faster. The default is not -single_module. A typical build of Python will have ~190 modules, when it could have just one. To check to see how many modules a dylib has, use otool - Mv on the dylib.

Note that this is NOT for building extensions, only for building the dylib for Python itself.
