Isn't it true that a TCP packet is typically 20 bytes, and a UDP packet about 8? This is minus any additional data that has been added to the packet. If this is true, then depending on the size of the pipe your sending the data through, and the amount of congestion there might be, a UDP packet would more easily and quickly hit its destination.
If your network is so congested that the difference between a min-sized TCP packet and a min-sized UDP packet matters, you have *bigger* problems... (In reality, most NICs will refuse to blat out a packet much smaller than 64 bytes or so - there was a number of info-disclosure issues with some drivers that would try to send a 56 byte packet, and failed to zero out the 8 trailing bytes).
