A lot of mobile devices have a limit to the bitrate of the video they 
can play. Ultrafast give minimal compression but high bitrate but also 
requires less processing power to decode.

Using ultrafast, you can reduce the quality using qp=<value>, reducing 
resolution matters more to reduce the bitrate.

Another alternative, you may use superfast, fast etc...
