             Summary: 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.
