> Hmm, Is this build on release mode?

Yes--in debug mode, each Py_INCREF is these 8 instructions:

========================
78BD071E  mov         ecx,dword ptr [_Py_RefTotal (79039700h)]  
78BD0724  add         ecx,1  
78BD0727  mov         dword ptr [_Py_RefTotal (79039700h)],ecx  
78BD072D  mov         edx,dword ptr [ebp-10h]  
78BD0730  mov         eax,dword ptr [edx]  
78BD0732  add         eax,1  
78BD0735  mov         ecx,dword ptr [ebp-10h]  
78BD0738  mov         dword ptr [ecx],eax  
========================

instead of just the one `inc` in release mode.
