> Ssh ControlMaster allowing to reuse connections can really improve responsiveness. Tip: start the master connection as a daemon (-f), so as not to mistakenly close the terminal which handles it, else you will close the channel for all other currently opened slave sessions. I wish ssh would fork and start the master on demand then close it when the last channel closes.
Good news: as of OpenSSH 5.6p1, it can. Just set "ControlPersist 60" in ~/.ssh/config (in addition to setting ControlMaster auto and ControlPath), and ssh will automatically spawn an SSH master connection in the background, and close it 60 seconds after the last client exits. (You can obviously change the timeout to taste.)
