So are you saying that using Tar over ssh would be a better option in this case? (Im not sure what netcat is)

rsync is surprisingly inefficient at file transfers. It's often several
times slower than even tar over ssh. try moving a big (several times larger
than RAM) over the network, using rsync, tar over ssh, and tar over netcat.
rsync will be by far the slowest.
