Agent computers host the virtual users that are run during tests. As many agent computers as necessary can be added to a project to support the required number of virtual users.
Agent computers are assigned to particular projects from the pool of agent computers that are available to the controller computer. The maximum number of virtual users who will run on each agent is computed automatically by Silk Performer; Alternatively, this number can be set manually. New agents can be added to the agent pool from the local area network or from other Windows domains; they are then available to be added to projects. Agents can be checked for availability, and agents can be removed from the pool.
