# (socat -u tcp4-listen:4123 - | tar xzp -C .) &
On source server, I run socat to feed incoming tar data to destination socat daemon where it listens on tcp port 4123. My destination server's ip adddess was 192.168.36.199 .
# (tar -czp - /mydir/1/ | socat -u - tcp4:192.168.3.199:4123)&
So, with a simple bash script I was able to run few socat daemons on destination server with different ports and feed them from source server to achieve higher data transer rate.
