When copying a directory that contains a lot of small files (like 1000+ files <1kB), it is faster to actually generate a tarball of the directory and have it unpacked on the fly on the destination server [2]:
# On DESTINATION box, launch first the listener
nc -l -p 2342 | tar -C /target/dir -xzf -
#On SOURCE box, launch the sender
tar -cz /source/dir | nc Target_Box 2342
