[FFmpeg-user] Low GPU utilization

I have noted that the following command
./ffmpeg -hwaccel nvdec -i ../4k_normal.mp4 -preset medium -movflags
+faststart -c:a aac ../4k_normal_conv.mp4
utilizes the GPU for about 20% according to nvidia-smi. That is pretty low
while 500MB out of 4GB of device memory is occupied.
Is that normal? Or there are some options missing here?
ffmpeg has a lot of options and I am confused about how to combine them. If
somebody can help, I will appreciate it.
