    Description

      This is a spin-off ticket from MB-44024, where timeouts are being seen from the SDK.
      Looking at KV we can see some very slow SELECT_BUCKET operations.

      These should be fast..

            Reran the test and no slow select buckets was reported (now with a lower threshold)
