IBM Rational Performance Tester can be used to test the IBM Lotus Notes standard client for assessing the scalability related issues on Citrix. For this issue, Rational Performance Tester Extension for Citrix Presentation Server is used to simulate the load generation to test the applications that are hosted on the Citrix Presentation Server.

The success of this artificial load generation is dependent on how you can mimic the behavior of the application which means the behavior of the application should be reproducible.Citrix performance tests interact with the Citrix Presentation Server client at a low level so that changes that you make to the test after the recording can change the context of the user actions and cause synchronization timeouts.
