+    - System takes approximately 30 seconds to load
+    - The longest service to load is "plymouth-quit-wait.service"
+
+2. `uptime`
+    ```
+    23:07:46 up  1:47,  1 user,  load average: 0,74, 0,78, 0,73
+    ```
+    - Shows how long it needs for system to load
+
+3. `w`
+    ```
+    23:08:54 up  1:48,  1 user,  load average: 0,67, 0,76, 0,72
