+[[set]] dcc_sliding_window [<number>]
+======Description:======
+The [[DCC]] specification requires that data cannot be sent via a
+[[DCC SEND]] connection until all previous data have been acknowledged
+by the receiver.  For high latency/high bandwidth connections
+(ie, anything faster than 28.8k), this can have serious consequences
+on throughput because at least half of the time the connection is idle
+waiting for an acknowledgement to be returned.  Although strict conformance
+to the [[DCC]] specification requires that this value be set to 1 (and it is,
+as the default), there are no technical impediments to sending more than
+one packet of data at a time, and real world experience bears this out.
+Significant gains in throughput can be achieved by setting this value to
+two (2).  Values of 3 or more get modest gains compared to the next lower
+value.  You can set <number> to be arbitrarily high because EPIC will
+never send a packet of data if sending that packet will block.  Thus,
+setting this value to an absurdly high value (such as 1,000) will yield
+optimal throughput.
