TRAMP doesn't open any network connections at all. Instead it relies on ssh (or ftp if you're really old-school). Open up your ~/.ssh/config file and set "ControlMaster yes", "ControlPersist yes" and "ControlPath ~/.ssh/cp-%C" and ssh will multiplex all of your ssh sessions across as few unique tcp connections as possible. This will speed up scp and sftp connections as well.
