 We recommend at least four workers. Please check your current worker count with
 
 ```bash
-    sudo openproject config:get WEB_CONCURRENCY
+    sudo openproject config:get OPENPROJECT_WEB_WORKERS
 ```
 
 If it returns nothing, the default worker count of `4` applies. To increase or decrease the worker count, call
 
 ```bash
-    sudo openproject config:set WEB_CONCURRENCY=number
+    sudo openproject config:set OPENPROJECT_WEB_WORKERS=number
 ```
 
 Where `number` is a positive number between 1 and `round(AVAILABLE_RAM * 1.5)`.
