IBM Rational Performance Tester

Tool Review

IBM Rational Performance Tester

Performance Tester is a performance testing tool used to identify the presence and cause of system performance bottlenecks.

Introduction

• Identify the presence and cause of system performance bottlenecks
• Create code free tests quickly without programming knowledge
• Provides a rich, tree-based test editor that delivers both high-level and detailed views of tests
• Automates identification and management of dynamic server responses
• Enables Windows, Linux and mainframe technology-based test execution
• Reports in real time to enable immediate recognition of performance problems and renders an HTML browser-like view of Web pages in the test
• Supports load testing against a broad range of applications such as HTTP, SAP, Siebel, SIP, TCP Socket and Citrix
• Operating systems supported: Windows, Linux

Features

• Script less Testing
• Find and diagnose the cause of performance problems
• Integrated Resource Monitoring

Benefits

• No programming knowledge is necessary to create, comprehend, edit or execute a performance test. Tests are displayed as hierarchical list of the Web pages that will be visited during execution. While test complexity is masked by default, advanced testers have access to all transactional information such as underlying page elements and server responses
• Rational Performance Tester goes beyond problem identification to problem diagnosis. Using Root Cause Analysis features, you can identify both the source code and physical application tier that is causing the bottleneck. With the generated UML sequence diagrams you can trace all activity that occurred just prior to the bottleneck to truly enable you to address the root cause of your performance problem
• Testers must be vigilant to detect performance and reliability problems that can be traced to hardware issues. IBM Rational Performance Tester can collect and display multiple resource statistics from any tier of the system under test, thereby exposing hardware related bottlenecks responsible for poor performance
