Abstract
Wepresent an approach to application-level performance
testing. This uses a popular test tool, TPNS
(Teleprocessing Network Simulator) to simulate
performance of an application. Our approach hinges
upon a simple prototype tc verifjl that the system
peformance falls within acceptable bounds. Once the
initial prototype is developed, detailed tuning mav take
place. We present a case study in which we tested the
performance of a large finance application. This
approach led to critical performance tuning
improvement. Due to this improvement, the average user
response time in our simulations was reduced from 30
seconds to under 1.5 seconds. This simulation has been
