#Step 0: fill this shit out

#source directory path wehere you are currently located

#destination [email protected]:/path/to/your/dest/dir
DEST="/path/to/dest/dir" 
#number of simultaneous rsync connections
#dont be stupid about this or it will be slower than 1 rsync
CON=10
##################################
#Step 1 change into the source dir

cd $SRC;

#Step 1 execute rsync with xargs

#Step 2 	#execute this command
ls $SRC |xargs -n1 -P$CON -I% rsync -Pa % $DEST

I suppose the easiest solution would be to execute this script via ssh on the remote server and make the destination the local machine
