Note that HammerDB stores all output of a workload called Jobs within a SQLite database for later retrieval. As a test workload prints a considerable amount of output for performance you can disable the storage of the Jobs under the Jobs tree view option, clicking Jobs Disabled and restarting HammerDB. If you leave Jobs enabled it is expected that the performance of the test workload is slower as all of the output is stored in SQLite.
