+## Fab-manager for small configurations
+
+If your server machine is not powerful, you can lower the system requirements by uninstalling ElasticSearch.
+In order to remove ElasticSearch, you must **first** disable the statistics module from Customization > General > Modules.
+
+Then, you can remove the `elasticsearch` service from the [docker-compose.yml](../setup/docker-compose.yml) file and restart the whole application:
+```bash
+docker-compose down && docker-compose up -d
+```
+
+Disabling ElasticSearch will save up to 800 Mb of memory.
