TransferQueueBundler: bundler thread should remove chunks of messages --------------------------------------------------------------------- Key: JGRP-2076 URL: https://issues.jboss.org/browse/JGRP-2076 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Priority: Minor Fix For: 3.6.10, 4.0 Currently, the bundler thread in TransferQueueBundler removes messages from the queue one by one: {code:java} while(null != (msg=queue.poll())) { long size=msg.size(); if(count + size >= transport.getMaxBundleSize()) sendBundledMessages(); addMessage(msg, size); } {code} This is inefficient, as we need to acquire the lock on ArrayBlockingQueue every time. {{ArrayBlockingQueue.drainTo()}} should be used instead, to remove as many messages as are in the queue with one lock acquisition.
