Some ansible playbook TASKS do run exceptionally slow

Dear all,

after several installations of SAS Viya, I have came across one that it rebels on execution times. We have even created local mirror repos, but not helping.

I expecience that the slowness come always with the same tasks. Such as Install java, Install java config, instal libselinux-python, ... tasks that normally take seconds.

If you run the playbook with -vvv you can see the commands executed. Ansible lauches the commands in a way of "ssh....sudo....phython file.py". If I run manually the phython file.py command, it runs in normal times.

That fact made me think of a few things I saw, before SAS Viya, with Ansible playbooks:

- the versions before 2.3.2 had some issues with this

- cheking the passwordless ssh and public keys https://bbs.archlinux.org/viewtopic.php?id=165382 and ensuring no errors on sshd

- https://access.redhat.com/solutions/317173 - sss_ssh_knownhostsproxy

- https://www.reddit.com/r/ansible/comments/7w9uy6/ansible_tasks_are_extremely_slow_to_execute/ - more about DNS...

- and checked some ssh configurations.

Some tasks run a bit better now, but still, too slow. Specially the Install SAS Packages, which should be fast, with local miror repos, but it takes hours.

Any ideas?

Thank you in advance,

Kind regards,

Juan

@JuanS_OCS,

I would suggest opening a technical support track and I or my co-workers will be able to investigate that.

Hi there, thank you for your answer, and that quick,

yes, there is a ticket open. I will keep this thread updated and I will wait until there is a solution to accept it as such.
