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

I thought TRAMP overrides that setting in your SSH config.

> TRAMP uses the ControlMaster=auto OpenSSH option by default, if possible. However, it overwrites ControlPath settings when initiating ssh sessions. TRAMP does this to fend off a stall if a master session opened outside the Emacs session is no longer open. That is why TRAMP prompts for the password again even if there is an ssh already open.

It does and it becomes a bit annoying if you were already persisting sessions, but you can just tell emacs to use the same sockets that ssh sets up.
