Is Power user supposed to run the queries in the sequence as one single user?
Can I specify many users more than one?
Does it run the same query or multiple queries in a random order?
Yes the Power test is suppose to be a single user test and we don't suggest to just add more users otherwise every user will be accessing the same data at the same time. The Stream test is the TPC-H multiuser test. A project file can be downloaded from the BMF community. In the Stream test each user (or stream) has a defined query execution order as specified in the specification.
