Investigate why use of bounded cursor has regression than performance improvement

      As per my understanding, the bounded cursors can improve the performance of cursor operations by restricting their search range in the btree. But using these cursors in the server code has more performance regression than improvement.

      Investigate why the use of bounded cursors doesn't improve performance. If regression is expected, we need to document the use of these cursors in the location where they can improve performance.
