From my office in West London: 0m0.389s 0m0.320s 0m0.706s 0m0.321s 0m0.225s and with a ControlMaster alive: 0m0.218s 0m0.093s 0m0.100s 0m0.097s 0m0.096s > Where is this trick documented again?

Basically, you set a ControlPath in your .ssh/config - e.g. like so: ControlPath ~/.ssh/mux...@%h:%p and then when you feel like it, you can fire up a ssh connection like so: ssh -oControlMaster=yes -f -N bazaar.launchpad.net which will be a ControlMaster, by listening on an AF_LOCAL socket and allowing other ssh processes to multiplex their connection requests down the existing tunnel, avoiding TCP and SSH connection setup time. (-f - go to the background after connection established, -N - do not run any command ) It certainly speeds up, say, pulling all the branches in an entire LP sourcecode directory! Max.
