I would use this script I wrote that needs the socat package.

On the source machine:

tarnet -d wherefilesaretosend pass=none 12345 .

On the target machine:

tarnet -d wherefilesaretogo pass=none sourceip/12345

If the vbuf package (Debian, Ubuntu) is there then the file sender will show a data progress. The file receiver will show what files are received. The pass= option can be used where the data might be exposed (slower).

Edit:

Use the -n option to disable compression, if CPU is a bottle neck.
