You can use performance profiles to define response time
details for a stub over time.
About this task
You create performance profiles on stubs in Test Factory.
You can populate the data in the performance profiles manually or
by importing the data from a spreadsheet. After a stub has been published
to
IBM® Rational® Test Control Panel,
you can override response time settings that you define in a performance
profile , either when starting a stub run, or during the run.
