Negative performance impacts due to missing SSH Optimization Config

[pemsith]

ISSUE TYPE

• Bug Report

SUMMARY

The repository lacks SSH optimization configurations in the ansible.cfg file.
Specifically;
ControlMaster and ControlPersist options are not set in the ssh_args configuration. These options enable persistent SSH connections, which significantly improve performance by reducing the overhead of establishing a new connection for each task.
pipelining is not set to true. Enabling pipelining reduces the number of SSH operations required to execute tasks, further enhancing execution speed.
The absence of these optimizations impacts performance negatively, particularly in environments with many hosts or complex tasks.

EXPECTED RESULTS

The ansible.cfg file should include the following optimizations to improve SSH performance:

[ssh_connection]
ssh_args = -o ControlMaster=auto -o ControlPersist=60s
Enable Pipelining: Set pipelining to true in the [defaults] section:

[defaults]
pipelining = true

ACTUAL RESULTS
