for fun try this 1. tar + nc 2. rsync 3. scp

#1 is the fastest way to send because it keeps the buffers full in a consistent stream which allows tcp windows to grow as large as possible. 2 and 3 ( scp and rsync ) do round trip acks to the remote side which drastically slows things down, even if done in parallel.

Note that tar and rsync can handle sparse files, but scp doesn't.

Also, rsync will likely be faster if some files are already in the destination as it handles that intelligently as well as only transferring changed blocks from files.
