+Scheduler tuning arguments
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The scheduler minimum number of events that are processed can be increased to
+reduce per event overhead and increase internal burst sizes, which can
+improve throughput.
+
+* ``min_burst`` specifies the minimum number of inflight events that can be
+ moved to the next stage in the scheduler. Default value is 1.
+
+* ``refill_once`` is a switch that when set instructs the scheduler to deque
+ the events waiting in the ingress rings only once per call. The default
+ behavior is to dequeue as needed.
+
+* ``deq_burst`` is the burst size used to dequeue from the port rings.
+ Default value is 32, and it should be increased to 64 or 128 when setting
+ ``refill_once=1``.
