We're using salt and while it's incredible buggy still it's the most impressive system we've used so far. It's faster than anything else because it does not go through the process of signing in through ssh and creating a unix session.

That might sound like a boring detail but it opens up many possibilities by doing things like asking all machines for their system time and then doing something with it.

To speed up ssh login time, try adding the following to your ~/.ssh/config:

  Host *
    ControlMaster auto
    ControlPath ~/.ssh/auth/%r@%h:%p
    ControlPersist yes

For me this changes connection times from 1.7 seconds to 0.189 seconds when connecting to a host over the internet.

Interesting tip. Thanks!

Note that you might need to create the auth subfolder using `mkdir ~/.ssh/auth`, otherwise it might throw an error on connection: `muxserver_listen bind(): No such file or directory`

What does this do?

Maintains a persistent ssh connection to each host once the first is created. Any subsequent ssh commands will be sent over the existing channel, skipping the time-consuming handshake process.
