vPerformer is a web performance and load testing tool that can be used to assess the performance and scalability of your web applications. vPerformer allows you to evaluate 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 load testing 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
* An easy to use graphical user interface that can record web transactions based on user GUI interactions.
* Does not require a programming background. For users who wish to program their load testing scripts, vPerformer utilizes the industry standard JavaScript language.
* vPerformer is capable of simulating a large number of virtual users while placing a negligible load of its own on the hardware.
* Develop parameterized, data-driven, reusable load testing scripts.
* Multiple machines can be utilized as replay agents with a single point of control.
* Quality Assurance engineers can easily test the performance and scalability of web apps prior to deployment.
