      NodeJS-Version: 18.8.0

      Steps to reproduce?

      See attached simple file.
      -> Create some data (it seems like count is more important than size of the documents)
      -> Execute simple Find-Queries

      My times from the attached file:
      Node16:
      async iteration: 2.144s
      toArray: 2.080s

      Node18:
      async iteration: 2.606s
      toArray: 2.493s
