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.
As of Ansible 2.1.0 this option is enabled by default.
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.
In previous versions, this option was disabled because of a bad interaction
with some sudo configurations. If sudo was configured to 'requiretty' for
operation then pipelining would not work and ansible would fail to connect
properly. This could be remedied by removing '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 :doc:`playbooks_acceleration`::
It is recommended to leave this option enabled. If you are stuck with an old
version of ansible your first choice option should be to remove requiretty
from the sudoers configuration and only disable pipelining if you cannot do
that. Enabling this eliminates the need for :doc:`playbooks_acceleration`::
