Based on my experience managing hosts in different regions, I know how much ping affects the speed of Ansible playbooks. Running playbooks on hosts with pings of greater than around 150ms can be painfully slow, so I was curious to see how much improvement pipelining or Mitogen could give for hosts at a range of pings.
This task is run before playbook tasks, in order collect information about the remote host, such as ansible_os_family. This task can take a few seconds depending on the ping of the host, so I was interested to see if pipelining or Mitogen had any effect on this. 1e1e36bf2d
