vPerformer

vPerformer is a load and performance testing product designed to evaluate the performance and scalability of web applications. This software offers a simple and efficient way to assess how a web application responds when accessed by multiple concurrent users. By recording and replaying automated scripts that simulate virtual users, vPerformer allows you to measure the performance characteristics of your application.

One of the key benefits of vPerformer is its ability to monitor the state of external components that may affect your web application's behavior. This includes operating systems, web servers, application servers, database servers, network devices and SNMP implementations from various vendors.

Through this feature, you can easily identify performance bottlenecks and pinpoint the source of performance problems. vPerformer also comes equipped with a user-friendly graphical interface enabling users to record web interactions using point-and-click operations, without the need for a programming background. However, for users who prefer to program their scripts, vPerformer uses the industry-standard JavaScript programming language.

Another advantage of this software is its capability to simulate a large number of virtual users, while placing minimal strain on the underlying hardware. vPerformer also allows you to develop parameterized, data-driven and reusable scripts, and multiple machines can be utilized as replay agents with a single point of control.

Overall, vPerformer is a valuable quality assurance tool that enables engineers to test the performance and scalability of web applications before deployment. It's a software well worth exploring.
