Product description

Rational Performance Tester is a scripting-free environment for automating load and scalability testing of web, ERP, and server-based software applications. Rational Performance Tester provides rich and customizable reporting to help you identify the presence and cause of system bottlenecks. It captures the network traffic that is rendered when the application under test interacts with a server. This network traffic is then emulated on multiple virtual users while you play back the test.
