The values have the following meaning.
Table 4.9. Virtual User Options
|Virtual Users||The number of Virtual Users to create. Note that when running a Timed Workload HammerDB will automatically create an additional Virtual User to monitor the workload.|
|User Delay(ms)||User Delay(ms) defines the time to wait a Virtual User will wait behind the previous Virtual User before starting its test, this is to prevent a login storm with all Virtual Users attempting to login at the same time.|
|Repeat Delay(ms)||Repeat Delay(ms) is the time that each Virtual User will wait before running its next Iteration of the Driver Script. For the TPROC-C workload this should be considered as an 'outer loop' to the 'inner loop' of the Total Transactions per User in the TPROC-C Driver Script.|
|Iterations||Iterations is the number of times that the Driver Script is run in its entirety.|
|Show Output||Show Output will report Virtual User Output to the Virtual User Output Window, For TPROC-C tests this should be enabled.|
|Log Output to Temp||When enabled this appends all Virtual User Output to a text file in an available temp directory named hammerdb.log|
|Use Unique Log Name||Use a unique identifier for the Log Name.|
|No Log Buffer||By default text log output is buffered in memory before being written, this option writes the log output immediately.|
|Log Timestamps||Add an additional line of output with a timestamp every time that the log is written to.|
