Ansible pipelining

Ansible pipelining

Enabling pipelining reduces the number of SSH operations required to execute a module on the remote server,
by executing many ansible modules without actual file transfer.
This can result in a very significant performance improvement when enabled,
however when using “sudo:” operations you must first disable ‘requiretty’ in /etc/sudoers on all managed hosts.

By default, this option is disabled to preserve compatibility with sudoers configurations that have requiretty
(the default on many distros), but is highly recommended if you can enable it, eliminating the need for Accelerated Mode:

pipelining = False

pipelining = True
control_path = /tmp/ansible-ssh-%%h-%%p-%%r
