Hi Team,

This mail is regarding the CPU utilization of the Ansible

I have a Centos (version 8) Machine where Ansible is installed ( 4CPU and 16GB RAM) Executing 2 to 3 parallel calls takes up to 100% CPU

Help us to know if any optimization can be done here

Setup details

**Machine where Ansible is installed**

Centos 8

Ansible version

ansible [core 2.11.12]

config file = None

configured module search path = [‘/root/.ansible/plugins/modules’, ‘/usr/share/ansible/plugins/modules’]

ansible python module location = /usr/local/lib/python3.7/site-packages/ansible

ansible collection location = /root/.ansible/collections:/usr/share/ansible/collections

executable location = /usr/local/bin/ansible

python version = 3.7.16 (default, May 3 2023, 10:58:47) [GCC 11.2.1 20220219]

**remote host details**

windows 2019 4CPU and 16 GB RAM

**Command used to Execute**

ansible-playbook -i /tmp/ansible\_adapter/inventory/hostinventory ./helloworld.yaml -vvv

we use NTLM way of Authentication to Windows host

Play book is written like this

Play book is written like this

- hosts: all  
tasks:
- name: Execute the executable  
win\_command: helloworld.exe  
register: host\_output
- set\_fact:  
result: “{{ host\_output.stdout }}”  
err\_details: “{{ host\_output.stderr }}”  
cacheable: yes
- debug:  
var: host\_output.stdout\_lines

Thanks
