IBM Rational Performance Tester

Go for IBM RPT if:1. You're testing a Java-based Web application with HTTP protocol2. You wanted to distribute the load across machines easily 3. Your team is in learning phase/not really introduced to a wide range of performance testing toolsDo not go for IBM RPT if:1. You wanted to test REST or any other advanced protocols2. Your system under test demands a very high user load3. Your application is written in .NET or any other platform except Java.

Cons

  • Memory utilization could have been improved.(Eats up system's RAM)! It may crash if a test is conducted with the heavy load if adequate RAM is not available in the VM/host machine.
  • Licensing could have been made simpler. IBM's licensing method is difficult to follow.
  • Support for protocols other than HTTP. Not really up to the current trend.

Alternatives Considered

Cost/Licensing: While JMeter is an opensource testing tool from Apache, compared to IBM RPT and HP LoadRunner, RPT is much cheaper than Loadrunner.Functionality: JMeter provides basic functionalities which are adequate for performance testing, however advanced features are not available (such as load testing with GUI, reporting is very basic etc.). But when it comes to Loadrunner, it offers very broad features and supports a variety of protocols. So in this category, Loadrunner is a winner, but RPT is better than JMeter.Ease of operating: JMeter is easy compared to LoadRunner, but it has old GUI and look and feel is not that great to understand. Also, most of the things are to be done in a command line, non-GUI mode. While LoadRunner is very advanced with many options, which also confusing sometimes. But RPT, on the other hand, maintains a balance between simplicity and offering of different features. So winner: RPT.
