I have done testing with file transfers using both TCP and UDP,

That could have disastrous consequences for the rest of the
TCP (was: newbie check..)

The killer on high latency links is the tcp-window and the continual
wait for ack. With links above 1000ms this compounded delay reduces
the available bandwidth to a very small percentage of the interface

That could have disastrous consequences for the rest of the traffic on that
link.
