Configuring Control Settings

In the Silk Performer menu, click Settings > System .

Click the Control tab.

The Virtual users area provides the following options:

Enable Automatic calculation to let Silk Performer calculate the number of virtual users per process.
Disable Automatic calculation to manually enter a value into the Virtual users per process field.
In the Stop virtual users after __ transaction failures field, enter the number of transaction failures after which virtual users should be stopped.

Note: Virtual user settings are only stored on a per-project basis. You must have a project open to enable this setting. After a project is loaded, the options apply only to the specific project configured with that setting.

The Remote agent communication area provides the following options:

Select LAN to optimize the controller-agent communication for a local area network.

This is especially useful if all of the agent computers you are going to use for your load tests are located in the same local area network and all are using a fast connection.
Select WAN to optimize the controller-agent communication for a wide area network.

This is especially useful if you are going to use many agent computers that are located somewhere on the Internet.
Select Custom to specify your own parameters.
Note: Use the Custom option only if you run into problems with LAN or WAN settings.

In the Connect field, enter the time, in which the controller computer should try to establish a connection to each remote agent computer. If the connection cannot be established within this time interval, Silk Performer reports an error.

Note: It is not recommended to change this setting.

In the Ping Interval field, enter the time, within which the controller computer should attempt to retrieve load test status data from the agent computers. The controller computer requests this information from the agent computers whenever the contents of the Monitor window need to be updated. If the agent computer fails while receiving data during this time interval, Silk Performer will report a warning.

Note: It is not recommended to change this setting.

In the Command field, enter the time in which the controller computer should try to send a command to a remote agent computer. If the command cannot be sent within this time interval, Silk Performer reports an error.

Note: It is not recommended to change this setting.

Enable the compressing and caching options if necessary. For more information, read Compressing Data Files and Caching Data Files.
