You can use LoadRunner to measure response time at different points in the
client/server system. Determine where to run the Vusers and which Vusers to run
according to the test objectives:
Measuring end-to-end response time:
You can measure the response time that a typical user experiences by running a
GUI Vuser or RTE Vuser at the front end. GUI Vusers emulate real users by
submitting input to and receiving output from the client application; RTE Vusers
emulate real users submitting input to and receiving output from a character-
based application.
You can run GUI or RTE Vusers at the front end to measure the response time
across the entire network, including a terminal emulator or GUI front end, network
and server.
