             Summary: Table.add() with message list can lead to many resizings
                 Key: JGRP-1769
                 URL: https://issues.jboss.org/browse/JGRP-1769
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 3.5


Table maintains an array of arrays (a matrix) and needs to resize it when adding messages that would go beyond the capacity of the array.
This is done when adding a message.
However, when adding a *list of messages*, as we're adding messages individually, we compute the needed capacity and perform a resize if needed.
This leads to possibly too much copying.
SOLUTION:
* When adding a list of messages, do the resizing (if needed) *before* adding messages individually
