      Description

      Performance tests showed that due to some contention, increasing the number of threads beyond 16 has no positive impact in performance while having a negative impact on memory consumption by requiring more buffers. This excessive memory consumption can have some serious impact when the import/rebuildIndex is running on an online DJ instance.
      More over, the offHeapSize argument added in OPENDJ-2727 is confusing for the end-user and should be removed.
