Our support department wants to know what type of load is placed on the terminal server with x number of sessions opened. Silk Performer will not do this (I don't think). We need to have x number copies of the GUI to sumilate the actual numer of people that will have connections to the terminal server and see where will need to put more hardware. If I remember correctly, Silk Performer captures the communications that is going on between the application the the middle or db layer. When running the test, you bypass the GUI to simulate the users.
