The transaction counter will be displayed and continually sample and display the transaction rate during the test. It is important to note that the transaction rate is sampled with the SQL detailed above for the database selected and therefore all transactions on the database are sampled whether from HammerDB or another application running at the same time. Similarly if 2 or more instances of HammerDB are run against the same database at the same time, the cumulative transaction is sampled.
