 1. Replacing Ansible `import_tasks` calls with `include_tasks`, which decreased runtime in half. Using `import_tasks` is slower and causes Ansible to go through and skip way too many tasks (tasks which could have been skipped altogether by not having Ansible include them in the first place). On an experimental VM, **deployment time was decreased from ~530 seconds to ~250 seconds**.
 
-2. Introducing new `install-*` tags (`install-all` and `install-COMPONENT`, e.g. `install-synapse`, `install-postmoogle`), which only run Ansible tasks pertaining to installation, while skipping uninstallation tasks. In most cases, people are maintaining the same setup or they're *adding* new components. Removing components is rare. Running thousands of uninstallation tasks each time is wasteful. On an experimental VM, **deployment time was decreased from ~250 seconds (`--tags=setup-all`) to ~100 seconds (`--tags=install-all`)**.

 You can still use `--tags=setup-all`. In fact, that's the best way to ensure your server is reconciled with the `vars.yml` configuration.
