IBM DevOps Test Performance vs. T-Plan

Go for IBM RPT if: 1. You're testing a Java-based Web application with HTTP protocol 2. 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 tools Do not go for IBM RPT if: 1. You wanted to test REST or any other advanced protocols 2. Your system under test demands a very high user load 3. Your application is written in .NET or any other platform except Java.

• Live Monitoring of Performance Testing Metrics
• Easier Test Data Parameterization
• Performance Tests Scheduler
• Server Resource Monitoring
• Great Reports that can be Exported as HTML Reports

• 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.

IBM Rational Performance Tester is better in many aspects when compared to Apache JMeter. For example, you have ready made scripts to assist you, You have better monitoring of different performance metrics and can generate better reports that can be exported as HTML. The only downside of IBM RPT is that it can be very costly at times while JMeter is for free which is a huge advantage. That's why we try using in our organization a combination of both as much as we can.

• Accuracy in metrics, thus improving system's performance
• Costs less compared to competitor like HP LoadRunner
• Helped the team of beginners learn things quickly
