Would it be better to use RTP rather than just udp?

It is very important that the delay for the entire process be as minimal as possible. I have been experimenting with different ffmpeg commands but have not been able to reduce the delay beyond about 2 seconds. Right now, the command that give the best performance is:

>> ffmpeg -f dshow -i video="screen-capture-recorder" -f mpegts udp://host:port
