WAPT Pro is a professional version of the popular load, stress and performance testing tool for websites and web-based applications. It preserves all the benefits of the regular version, including its ease of use, ability to create comprehensive tests in a matter of minutes, flexible specification of virtual user behaviour, descriptive graph and reports for test results. At the same time the product includes several features required for testing of high performance servers, web applications that transfer large amounts of multimedia data, and applications severely depending on the database productivity. The product can use several different computers to create required test volume. Each system participating in the test runs a special service called WAPT Load Agent. They all are managed from a workstation running WAPT Pro Workplace component.
