[jboss-jira] [JBoss JIRA] Commented: (JGRP-517) TP.send() creates a new ByteArrayOutputStream for every message

Bela Ban commented on JGRP-517:
-------------------------------

I had this before, and called reset() on the output stream. However, if we for example send a larger message (say 60K), then we end up with a 60K buffer allocated even though it may not be used later on as we're sending smaller messages. Performance wise, both solutions were the same.

> Every call to TP.send() results in a new ByteArrayOutputStream being created. This creates a large amount of garbage. Could TP.send() use a pool of ByteArrayOutputStreams or something to cut down on generated garbage?
