We performed a comparison between Apache JMeter and IBM Rational Performance Tester based on real PeerSpot user reviews.
Find out what your peers are saying about Apache, OpenText, Tricentis and others in Performance Testing Tools."The biggest thing I liked about it is that there is a huge user base out there, and being shareware and being Apache, if I have any question on how to get something done, I get 18 different answers. Out of those, there would be at least a few good approaches for what I was trying to do. So, the support system out there is most valuable."
"The most valuable feature for us is the available information on the forums and to be able to discuss and get answers from the people that are involved in using this tool."
"To me, what's most valuable in Apache JMeter is that it's a lightweight tool for application testing. It's the best load-testing tool for my company because Apache JMeter simulates your application during testing. Apache JMeter also creates threads with good server utilization. Apache JMeter allows you to focus on analyzing the situation, looking into measurements, response time, and client-server responses, which I find valuable."
"When someone in our organization wants to test web applications, they use Apache JMeter since they face no hurdles while using the solution."
"We are using this for performance testing and some automation."
"The most valuable feature of this solution is being able to launch many requests and scheduling simulating human interactions with the application."
"Apache JMeter is stable."
"The most valuable features of Apache JMeter are user-friendliness, large resource, and the quality of assistance they provide. Additionally, it is easy to integrate with cloud platforms, such as AWS."
"It can support both web applications and mobile applications, and in certain cases, it can also support testing of desktop applications or software-based applications. You can write web applications, mobile applications, and software-based applications."
"Technical support is very good. I'm very satisfied with the assistance we've received so far."
"Running JMeter in GUI mode uses a lot of memory, which means we need to switch to a non-GUI mode when using a heavy load."
"The only thing is the learning curve. It's high."
"Apache JMeter may have difficulty recognizing dynamic objects in some critical cases, which can lead to challenges in terms of object identification."
"The tool should be made a bit more robust, and better support should be made available."
"Report generation needs to be improved. It is quite difficult to get to."
"JMeter is lagging when it comes to GUI performance testing because we need to install some third-party plugins for recording the GUI script, and the performance isn't very reliable."
"The solution's setup could be easier and security could be improved to minimize vulnerabilities."
"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies."
"The solution is not easily scalable. If you want to extend the solution, you need to purchase a different kind of license. You also have to work with the IBM team to assist in scaling."
