+### Performance tuning
+
+Refer the following:
+
+- [8 ways to speed up your Ansible playbooks]
+- [6 ways to speed up Ansible playbook execution]
+- [How to speed up Ansible playbooks drastically?]
+- [Easy things you can do to speed up ansible]
+
+Suggestions:
+
+- Optimize fact gathering:
+
+  - Disable fact gathering when not used.
+  - Consider using smart fact gathering:
+
+    ```ini
+    [defaults]
+    gathering = smart
+    fact_caching = jsonfile
+    fact_caching_connection = /tmp/ansible/facts.json  ; /tmp/ansible to use the directory and have a file per host
+    fact_caching_timeout = 86400
+    ```
+
+  - Only gather subsets of facts:
+
+    ```yaml
+    - name: Play with selected facts
+      gather_facts: true
+      gather_subset:
+        - '!all'
+        - '!min'
+        - system
+    ```
+
+    Refer the [setup module] for more information, and the [setup module source code] for available keys.
+
+- Consider increasing the number of forks when dealing with lots of managed hosts:
+
+  ```ini
+  [defaults]
+  forks = 25
+  ```
+
+- Set **independent** tasks as async.
+- Optimize SSH connections:
+
+  - Prefer key-based authentication if used:
+
+    ```ini
+    [ssh_connection]
+    ssh_args = -o PreferredAuthentications=publickey
+    ```
+
+  - Use pipelining:
+
+    ```ini
+    [ssh_connection]
+    pipelining = True
+    ```
+
+  - Consider using multiplexing:
+
+    ```ini
+    [ssh_connection]
+    ssh_args = -o ControlMaster=auto -o ControlPersist=3600s
+    ```
+
+- Consider installing and using the [Mitogen plugin][mitogen for ansible] on the controller:
+
+  ```sh
+  curl -fsLO 'https://github.com/mitogen-hq/mitogen/releases/download/v0.3.7/mitogen-0.3.7.tar.gz'
+  tar -xaf 'mitogen-0.3.7.tar.gz'
+  ```
+
+  ```ini
+  [defaults]
+  strategy_plugins = mitogen-0.3.7/ansible_mitogen/plugins/strategy
+  strategy = mitogen_linear
+  ```
+
+  > Be advised that mitogen is not really supported by Ansible and has some issues with privilege escalation
+  > ([1](https://github.com/mitogen-hq/mitogen/issues/466)).
+
+- Improve the code:
+
+  - Bundle up package installations together.
+  - Beware of _expensive_ calls.
