[jboss-jira] [JBoss JIRA] Created: (JGRP-1223) STREAMING_STATE_TRANSFER abysmally slow

STREAMING_STATE_TRANSFER abysmally slow --------------------------------------- Key: JGRP-1223 URL: https://jira.jboss.org/browse/JGRP-1223 Project: JGroups Issue Type: Bug Affects Versions: 2.8 Environment: Windows XP Reporter: Kornelius Elstner Assignee: Bela Ban With a relatively large shared state (anything in excess of a few MBytes) STREAMING_STATE_TRANSFER is very slow, it can take minutes for the state transfer to complete. The underlying issue is that STREAMING_STATE_TRANSFER.StreamingOutputStreamWrapper subclasses java.io.FilterOutputStream which always calls write(int b), even if buffers are to be written to the underlying socket. As a consequence each byte to be transferred results in a call to write() to the underlying socket. The fix is simple, the byte array variants of StreamingOutputStreamWrapper.write() should delegate to the wrapped socket directly. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
