      Description

      The capped collection implementation in WiredTiger starts doing a cursor truncate once collections reach the configured maximum size. That's efficient if we are removing ranges of data, but not if only removing a few data items.

      We should review the implementation to see if we can improve the performance of capped collections with WiredTiger.

      Some work was done on this in SERVER-32424.
