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 stable."
"It is scalable. You can scale up to 1,000 users in JMeter. If you can put up four slave servers, you can easily ramp up to 1,000 users."
"The solution is free. You don't need to worry about licensing costs."
"The solution has good transition controllers and distributed testing."
"We really appreciate that the solution comes with a live community, which continuously provided plugins and support protocols."
"The solution helps by detecting bottlenecks."
"The reports and analysis tools are very good. They are the solution's most valuable features."
"The solution is scalable."
"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."
"The plug-ins make the reports heavy and they have to be run in non-GUI mode."
"The user interface is a little bit tricky."
"The stability could be a bit better."
"It's not easy to get the data from one place or to do customizations."
"At present, if the number of virtual users increases beyond 10,000 when testing, then it results in a Java heap which causes the solution to crash."
"We would like some reporting and analysis tools to be added to this solution."
"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."
"Because so much is being done these days with authentication processes, a better system for either getting bearer tokens or some kind of token-based authentication prior to executing APIs would benefit the product. It is there, and you can do things. It is just not real clean at this point. There should be a better authentication process for JMeter or some automation or better guidelines for gaining and utilizing tokens on the fly."
"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."
