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."Apache JMeter is quite flexible."
"JMeter is easy to use for a user who doesn't have too much knowledge of programming or certain languages."
"It's easy to set up."
"The solution has good transition controllers and distributed testing."
"The thread groups, samplers, and listeners, which are all determined by the script's requirements, are the most valuable features of this solution."
"This solution is very user-friendly, and allows for a lot of data capture when testing."
"We are using this for performance testing and some automation."
"The solution is scalable."
"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."
"Self-healing and page rendering for the end-users are not available in Apache JMeter."
"It has some proxy-based dependencies which require specific proxies to be set up or disabled, which causes problems."
"It should be easier to combine multiple scripts. If you have multiple scripts, you need to write a new script to combine those scripts. The virtual user generator is slow."
"We would like more documentation to be provided for the advanced level features that are available in this solution, in order to improve development."
"It's not easy to get the data from one place or to do customizations."
"Given that Apache JMeter is a free and open-source tool, documentation improvement may not be a major concern, as it is mostly contributed on a voluntary basis. The essential information is already available. However, in terms of the interface, there are occasional bugs, and the tool may not address them as quickly as some users would like. Fixing defects and bugs might take a considerable amount of time, with users sometimes having to wait for several months or even a year for the next release to address specific issues."
"Apache JMeter may have difficulty recognizing dynamic objects in some critical cases, which can lead to challenges in terms of object identification."
"In future releases, it would be helpful if there was an integration with ALM Octane."
"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."
