+[WARNING]
+====
+The installer caches playbook configuration values for 10 minutes, by default. If you change any system, network, or inventory configuration, 
+and then re-run the installer within that 10 minute period, the new values are not used, and the previous values are used instead. 
+You can delete the contents of the cache, which is defined
+by the `fact_caching_connection` value in the *_/etc/ansible/ansible.cfg_* file. An example of this file is
+shown in xref:../../scaling_performance/install_practices.adoc#scaling-performance-install-optimization[Recommended Installation Practices].
