public ushort MaxSentMessageQueueSize ;


Defines maximum number of messages that can be held in the queue for sending. Default value = 128.

This buffer serves to smooth spikes in traffic and decreases network jitter. If the queue is full, a NoResources error will result from any calls to Send(). Setting this value greater than around 300 is likely to cause significant delaying of message delivering and can make game unplayable.
