Rational Robot Question:

Rational Testmanager is a sophisticated tool that can be used for automating performance tests on client/server systems. A client/server system includes client applications accessing a database or application server, and browsers accessing a Web server.
Performance testing uses Rational Robot and Rational TestManager. Use Robot to record client/server conversations and store them in scripts. Use TestManager to schedule and play back the scripts. During playback, TestManager can emulate hundreds, even thousands, of users placing heavy loads and stress on your database and Web servers.
