      Description

      "idx miss %" field was a steady zero, whereas updates of a 1-2 rows in a 1 million collection were totally slow.

      the update's specification was something like

      {my_array_field : an_element_that_should_be_present_in_the_array}

      after an index was added for the array field, the process finished blazingly fast.
