+       This setting should only be used if you know what you are doing!
+       It controls the time in msec. between two status requests to MPD.
+       To high values (long time) will make mpdevil very slow in terms
+       of showing the latest status of MPD (e.g. current song).
+       To low values (short time) can cause gui blocks making mpdevil
+       unresponsive and cpu intensive.
