      Start an in-Memory instance (I have verified the problem with both standalone and RS).
      Load some data in any collection.
      db.stats() and db.c.stats() shows index size to be 4096 independently of the collection size. If several index are created, each one is 4096 bytes size.

      Playing with 3.2.0-rc4 I have found that the db.stats() command is always informing the size of indexes as 4096 bytes.

      MongoDB Enterprise inMem:PRIMARY> db.stats()
{
	"db" : "POCDB",
	"collections" : 1,
	"objects" : 1876714,
	"avgObjSize" : 285.37579247557164,
	"dataSize" : 535568745,
	"storageSize" : 535568745,
	"numExtents" : 0,
	"indexes" : 1,
	"indexSize" : 4096,
	"ok" : 1
}

      This is also affecting compass index size report.
