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."I use all the tools, but one feature that stands out is JMeter's ability to test when services are sending a particular kind of request. We are using specific ports to send queries, and assess the performance based on the time it takes these queries to respond. You can use it with stuff other than the web performance."
"It is cost-effective and simple to use."
"The most valuable feature in JMeter is the Thread Group, which helps us to see whether the performance is good."
"The scripting ability is most valuable. It is easy to use. There is a UI, and you can go in there and figure those things out. After you've got a good set of tests, you basically have a scripted document that you can grab and execute in a pipeline. It is pretty quick to set up, and you can scale it and version control it."
"The recording and playback functionality is helpful."
"Apache JMeter is stable."
"I appreciate JMeter's simplicity and power for performance testing."
"The most valuable feature of Apache JMeter is its popularity. It is the best open-source tool with all the features needed."
"Technical support is very good. I'm very satisfied with the assistance we've received so far."
"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."
"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 installation needs some work. It could be simplified."
"It has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems."
"I need to consider it further because as features increase, it might become more complicated, and my goal has always been simplicity. Currently, I have to focus on other tasks, and I'm handling multiple responsibilities, so I can't juggle everything at once. However, if you ask me, I believe EJB covers most functionalities that are crucial. One improvement I'd suggest is adding a graphical aspect to the Gateway, making it a bit more colorful. Unlike JMeter, which lacks color, having a bit of color in the graphical aspects would be beneficial. Overall, for the essential features, EJB should work fine."
"Automation is difficult in JMeter."
"Apache JMeter may have difficulty recognizing dynamic objects in some critical cases, which can lead to challenges in terms of object identification."
"You really need a technical team in order to really utilize the product."
"In terms of platform support, they need to extend the support for backend platforms and more of the legacy types of platforms."
"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."
"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."
