+## Direct TCP network transfer
+
+If ssh-encryption performance is too slow for your use-case, you can do a direct unencrypted transfer via tcp ip:
+
+Use something like this:
+```console
+zfs-autobackup ... --send-pipe "nc server_name 8023" --recv-pipe "nc -l -p 8023"
+```
+
+This will pipe the data through netcat on the specified port.
