data on how slow ansible actually is when compared with Puppet

 * [tags](https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_tags.html) can be used to run a subset of a playbook but also skip

   certain parts

Finally, Ansible is notoriously *slow*. A [relatively simple Ansible

playbook](https://salsa.debian.org/anarcat/prometheus.debian.net) to deploy Prometheus runs in 44 seconds while a

fully-fledged Puppet configuration of a production server runs in 20

seconds, and this includes a collection of slow facts that takes 10 of

those 18 seconds, actual execution is nearer to 7 seconds. The Puppet

configuration manages 757 resources while the Ansible configuration

manages 115 resources. And that is with [ansible-mitogen](https://packages.debian.org/unstable/ansible-mitogen): without

that hack, the playbook takes nearly two minutes to run.

In the end, the main reason we use Fabric instead of Ansible is that

we use Puppet for high-level configuration management, and Ansible

conflicts with that problem space, leading to higher cognitive
