    Description

      http://groups.google.com/group/mongodb-user/browse_thread/thread/ded206b11dd9a31f

      In a nutshell, all (slave?) nodes in a replica set cache the same documents, because Mongos spreads the load across all slave nodes. This causes severe cache duplication, which leads to wasted resources (RAM) and increases IO load.
