When running the gpu background subtraction example from the official OpenCV repository, I notice that the FGD algorithm is particularly slow, even with an NVIDIA Quadro K4000.

It clocks in at about 10 fps on full HD (1920x1080) videos, whereas MOG and MOG2 can do 150+ fps, and even GMG does about 60 fps.

Is that normal?
