 * _renderaccelerateinterval_ : this setting, a floating point value in seconds, is used as the _renderinterval_ value when the length of the tile update queue exceeds _renderacceleratethreshold_ tiles in length.
 
+* _tiles-rendered-at-once_ : this setting controls the maximum number of update tiles that will be rendered concurrently.  If not defined, the value defaults to 1/2 the number of processor cores.  Settting this to lower values can reduce peek CPU use when large tile update load occur (from newly generated chunks, for example).
+
 * _zoomoutperiod_ : this setting, an integer value in seconds, specifies how often update processing of zoomed-out tiles is done.  This done to prevent unneeded regeneration of the tiles due to repeated changes by players (such as when mining).  Default value is 60 seconds.
 
 * _enabletilehash_ : this setting, a boolean, is used to enable the use of tile content hash codes, which are used to avoid re-encoding tiles that have not changed in value after re-rendering (such as due to changes in blocks that are not visible on the tile).  This reduces processing load, zoom-out processing, and communications traffic with web clients.
