The Silk Performer licensing model is based on virtual users (VUsers).
Starting and using the Silk Performer Workbench does not require a license. You can model and customize scripts as well as adjust many other load test settings without a license. Also, executions that are performed with only one virtual user (like try script or baseline executions) do not require a license.
Starting a load test run requires licenses for the virtual users employed in the execution.
Silk Performer offers two licensing models:
When you upgrade from an older Silk Performer version, new licenses are required for executing load tests with the new version. During the upgrade process, you can keep the old licenses for a period of 90 days.
Silk Performer works with three types of VUsers. Each type allows to simulate different application types:
