I've achieved over 10x performance improvement (with full YOLOv3) in Python on a Raspberry Pi 3B+. It now analyzes sending security images on 24/7 motion detection (the CNN forward pass for full YOLOv3 is 548ms, add some CPU overhead to handle bounding boxes, etc.). I ordered a second one for a similar task on Pi 4.
