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."When someone in our organization wants to test web applications, they use Apache JMeter since they face no hurdles while using the solution."
"JMeter lets us generate virtual users and T-load, per our requirements. It's easy to configure and adjusting the virtual users according to the DPS we want to achieve."
"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."
"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."
"It's open source, so I like that about the product. And there's a lot of community support for it."
"The features that I appreciate are quite basic. It is easy to ramp up the threads and start calling the application. A lot of connectors can already be found within Apache JMeter, but we are not using the entire set because the integration between the customers and platform is based on HTTP. We are just going to produce lots of HTTP sequences."
"The solution helps by detecting bottlenecks."
"This solution is easier to use than any other tool in the market; there is not even a requirement to learn a lot of scripting in order to use it."
"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."
"Improving JMeter's sync time would be beneficial."
"The interface could be made more user-friendly."
"It will be much easier, and beneficial for the individual to run it on their own machines rather than having a high-end infrastructure, more CPUs, or more memory that has been consumed by Apache JMeter."
"The initial setup is complex and needs to be upgraded."
"At times when we overload the application, it gets stuck...After the solution gets stuck due to overloading, we have to restart our computers. In short, the solution keeps crashing."
"It should start supporting the presentation layer. It currently provides performance testing specifically at the application and API level. It can be extended to the presentation layer, which includes mainly Angular and React frameworks. It should also be easy to use and easy to train people."
"The only thing is the learning curve. It's high."
"In terms of setup, it could be nicer, to be honest. Sometimes, I get a little bit lost."
"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."
