HP LoadRunner is the industry-standard performance testing product for predicting system behavior and performance. Using limited hardware resources, LoadRunner emulates hundreds or thousands of concurrent users to put the application through the rigors of real-life user loads. Your IT group can stress an application from end-to-end and measure the response times of key business processes. Simultaneously, LoadRunner collects system and component-level performance information through a comprehensive array of system monitors and diagnostics modules. These metrics are combined into a sophisticated analysis module that allows teams to drill down to isolate bottlenecks within the architecture. LoadRunner supports the widest range of enterprise environments and is the only performance testing product to be customized and certified to work with ERP/CRM applications from PeopleSoft, Oracle, SAP, and Siebel.
