   Using multi-document transactions with a single-member replica set
   may have significant performance impact. Single-member replica sets
   should only be for testing/development purposes and are not
   recommended for production use.

   .. note::

      Multi-document transactions performance on a single-member
      replica set are not indicative of performance on a replica set
      with more than one member.
