vPerformer is a load and performance testing product that can be used assess the performance and scalability of your web applications. vPerformer allows you to assess how your web application responds when it is concurrently accessed by a large number of users. You can measure the performance characteristics of your application by recording and replaying automated scripts that simulate a large number of concurrent virtual users.

In addition to showing you the performance characteristics of your own application, vPerformer enables you to monitor the state of any associated external component that influences the behavior of your application. These components include operating systems, web servers, application servers, database servers, network devices, and SNMP implementations of various vendors. This allows you to identify performance bottlenecks and pinpoint the source of the performance problem.

Benefits:

A user-friendly interface based on point-and-click operations tremendously lowers the learning curve.
Does not require a programming background. For those users who wish to use their programming skills, vPerformer uses the industry standard JavaScript language
vPerformer can simulate thousands of virtual users while placing a negligible load of its own on hardware. Test engineers, without any programming expertise, can fully test the performance and scalability of web applications prior to deployment.
Develop customized, data-driven, reusable and goal-oriented test scripts for a highly productive testing process.
Flexibility of distributed testing with a single point of control.
Support for multiple platforms, browsers, web servers, application servers and database servers over a LAN or WAN.
