Hi,

[https://github.com/ansible/ansible/pull/485](https://github.com/ansible/ansible/pull/485) has a simple shell-out-to-ssh  
transport, that allows me to use GSSAPI authentication and other ssh  
features that paramiko doesn't support.

Unscientific benchmarks show that for a playbook with 11 tasks over 36  
nodes, it is significantly slower when not using anything extra, but  
is slightly faster when using ssh's features for that.

paramiko takes 1 minute and 59 seconds  
ssh takes 11 minutes and 54 seconds  
ssh with ControlMaster=auto takes 1 minute and 45 seconds

This is relevant to my interests. I might try and play with this soon.

yes..  
It works with proxycommand, controlmaster, etc. Any and all settings from the ssh config.
