Also, using persistent ssh connections makes a huge difference, esp. if you’ve got a heavy shell init on the local or remote side

  Host *
      ControlPath ~/.ssh/cm-%r@%h:%p
      ControlMaster auto
      ControlPersist 600

It's a good optimization, but be careful with it since it's not 100% compatible with the normal behavior. A master connection (the first one you establish) will not be able to close until all other connections have done so. Not all software can handle this correctly.
