copy files to a ssh server with gzip compression
Useful to move many files (thousands or millions files) over ssh. Faster than scp because this way you save a lot of tcp connection establishments (syn/ack packets).
If using a fast lan (I have just tested gigabyte ethernet) it is faster to not compress the data so the command would be:
tar -cf - /home/user/test | ssh user@sshServer 'cd /tmp; tar xf -'
If you can do better, submit your command here.
