Robbie Gemmell updated QPIDJMS-321:
-----------------------------------
Description: QPIDJMS-306 updated the message queue data structure to be
more efficient in use. The new versions has to grow itself several times to
reach the typical/default prefetch size as messages arrive. Given it is
relatively a small structure, it would be better to simply pre-size it to the
prefetch size and avoiding the growth. For any edge cases where it is desired
to keep the structure even smaller, the configured prefetch can be reduced, and
would already have had to be done anyway to satisfy the scenario. (was:
