A User type is a unique combination of a script, a user group, and a profile.
Silk Performer automatically generates all possible combinations of user types out of the available scripts, user groups and profiles. To have all user types that you need available, you must add the desired profiles to your test project beforehand. For example, to emulate three different bandwidths during your load test, you must first add a profile for each bandwidth.
The Find Baseline or the Define User Types dialog box allow you to assign user types to the active workload.
You can run a baseline test to establish the baseline performance of your load test for the selected user types. The different user types can be run at the same time.
Only one virtual user per user type is executed for the baseline test. The think times contained in the script are not randomized for comparison reasons.
