Dlib Face Detection is slow in windows 32bit

[Anand Sukumar]

I changed dlib face detection to camera module using opencv and having following FPS
Windows 64bit (Mingw 64) - FPS : 8-9
Windows 32bit (Mingw 32) - FPS : 3-4
Mac            - FPS : 8-10

I builded opencv and dlib in Release Mode
In windows 32 bit dlib face detection fps is very slow. Is there Issues in Architecture or anything else?
Can you please briefly explain the issue?
Please help me to solve this issue.Thanks in advance for Help!!!

Use a better compiler and enable AVX instructions. Also see:

I wonder that ,I build the same dlib code in windows 64 it getting good FPS ,Though I didnt enable the AVX instruction in opencv. I can't able to identify why it is slow in windows 32 bit.
Can you explain briefly? I am a newbie to OpenCV
