[jboss-jira] [JBoss JIRA] (JGRP-1337) ConnectionMap: getConnection() can be a bottleneck

ConnectionMap: getConnection() can be a bottleneck -------------------------------------------------- Key: JGRP-1337 URL: https://issues.jboss.org/browse/JGRP-1337 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Priority: Minor Fix For: 3.1 When multiple threads call TcpConnectionMap.Mapper.getConnection() to different target addresses, and some of those addresses are down, then the threads unnecessarily compete for the same lock, therefore socket creations to targets which are up might get delayed by socket creations to targets which are down. SOLUTION: move the actual creation of a socket out of the lock scope NOTE: getConnection() may not even need to acquire the lock as the calling code already acquired it.
