[jboss-jira] [JBoss JIRA] Commented: (JGRP-846) ExposedByteArrayOutputStream / ExposedDataOutputStream: override synchronized methods

ExposedByteArrayOutputStream / ExposedDataOutputStream: override synchronized methods ------------------------------------------------------------------------------------- Key: JGRP-846 URL: https://jira.jboss.org/jira/browse/JGRP-846 Project: JGroups Issue Type: Task Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.6.6, 2.7 Both of these classes have synchronized methods. However, JGroups (mainly in TP) locks an output stream (both for single messages and in the bundler), so we don't need synchronized methods. SOLUTION: overwrite the synchronized methods with unsynchronized methods in ExposedXXXOutputStream. The perf.Test shows an increase of perf from 95'000 1K messages/sec/node to 99'000 !
