+3.33. ds_timer_mode (int)
+
+   Specify the timer process to be used by the module for keepalives and
+   active dialogs tracking.
+
+   It can be set to:
+     * 0 - use main timer process.
+     * 1 - use secondary timer process.
+
+   On a server with a lot of traffic, using secondary timer can help with
+   performances, because the main timer can be overloaded by taking care
+   of transactions retransmissions and expirations of items in memory.
+
+   Default value is "0".
