This is more than two years old and it is possible that current FFmpeg git head contains more optimizations for arm (I don't know). If they exist, they should make a measurable difference. In any case, don't expect miracles, there is nothing obviously wrong with your command line, but you can always compare with x264 ultrafast, it may be faster, I never tested.
