    Description

      The MongoDB server uses the lookaside score statistic to make decisions about how much cache pressure is being generated by the required history window.

      There are cases where the lookaside score doesn't respond as expected to changes in behavior. We should investigate how to improve lookaside score tracking and the corresponding statistic.
