-*   Compress large payloads in all subscription adapters
+*   Compress large payloads in all subscription adapters with ActiveSupport::Gzip
 
-    This allows to broadcast payloads larger than 8000 bytes by compressing them with ActiveSupport::Gzip with PostgreSQL
-
-    ```yaml
-    production:
-      adapter: postgresql
-      channel_prefix: appname_production
-    ```
+    This will also help broadcast payloads on average 2 to 3 times larger on adapters such as PostgreSQL that has a size limit
