[jboss-jira] [JBoss JIRA] (JGRP-2146) UDP: multiple unicast and multicast receiver threads

UDP: multiple unicast and multicast receiver threads ---------------------------------------------------- Key: JGRP-2146 URL: https://issues.jboss.org/browse/JGRP-2146 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 4.0 By default UDP has one thread which reads from the DatagramSocket for unicast datagram packets and another one for reading packets from the MulticastSocket. Because each thread deserializes the received packet into a {{Message}} or {{MessageBatch}}, if a lot of packets are received, this may slow things down. The new attributes {{ucast_receiver_threads}} (default:1) and {{mcast_receiver_threads}} (default:1) in UDP can create multiple unicast- or multicast- receiver threads. Note that all threads of the same type compete for the lock on the DatagramSocket or MulticastSocket respectively, so setting these attributes to high values is probably detrimental as context switching will increase.
