    Description

          for (var j = 0; j < 20; j++) {
              for (var i = 0; i < 1000; i++) {
                  db["c"+i].insert({})
              }
              t = new Date()
              db.dropDatabase()
              print(new Date() - t)
          }
      

      Time required for dropDatabase progressively increases on each iteration, for example, with a 1-node replica set:

      The performance also starts off worse than 3.4.10.

      Does not reproduce standalone.
