IBM DevOps Test Performance helps software testing teams test earlier and more frequently by shifting testing left. IBM DevOps Test Performance validates the scalability of web and server applications, identifies the presence and cause of system performance bottlenecks and reduces load testing. Software testing teams can execute performance tests that analyze the impact of load on applications.
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 …

Chose IBM DevOps Test Performance
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 …
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.
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.
