Extensive Protocol Support and Precise Reporting Elevate Testing, Though GUI Usability Needs Improvement
The GUI of Apache JMeter is not that user-friendly because we have many proxies, and we have to record through the proxy. With the limited SSL we have, we cannot use it for UI, which is a drawback. However, Apache JMeter is really good for REST APIs. I don't think there are any other areas other than the GUI that I would want improved about Apache JMeter; it is generally good and supports multiple protocols.
KashifJamil - PeerSpot reviewer
Supports web and mobile applications, very scalable, very stable, and wonderful support
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of Apache JMeter include SCTP sampler, throughput controllers, stepping up thread group, parallel controller, timers, and the ability to use gRPC protocol."
"The metrics part of it and the ability to write your custom code to do some specific tests in the performance testing space are the most valuable features."
"We find the ease of use and the reports and graphs available valuable."
"Scripting with the solution is good."
"It is cost-effective and simple to use."
"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."
"It is scalable. It is cloud-based."
"One valuable feature of Apache JMeter is the ability to replicate scenarios where bulk files have to be uploaded via API."
"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."
 

Cons

"They should improve the solution on its UI front."
"The reporting is not very good."
"To the best of my knowledge, the documentation could be improved. It should be enhanced to better support newcomers. Currently, only people with some experience can easily understand the content. Including more sample programs, applications, and use cases would help many more people adapt to using the solution."
"The UI has room for improvement."
"The tool should be made a bit more robust, and better support should be made available."
"For UI automation, it is limited and therefore rates a one."
"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."
"What needs improvement in Apache JMeter is the very high load requirements when you want to scale it beyond certain thresholds. For example, small to mid-range testing is very easily done with Apache JMeter, but if you scale and increase the load, then it would be a problem because the tool consumes a lot of resources, probably because Apache JMeter provides an enriched UI experience, so it consumes a lot of memory and requires high CPU usage. This means you have to manage your infrastructure, or else you'll have high overhead expenses. As Apache JMeter is a heavyweight tool, that is an area for improvement, though I'm unsure if Apache can do something about it because it could be a result of the way it's architected. What I'd like to see from Apache JMeter in the future is for it to transition to the cloud, as a lot of cloud technologies emerge around the globe, and a lot of people prefer cloud-based solutions or cloud-native tools. Even if a company has a legacy system, it's still possible to transition to the cloud. I've worked with a company that was an on-premise company that moved to the cloud and became cloud-native. If Apache JMeter could transition to the cloud, similar to k6, then it could help lessen the intense resource consumption that's currently happening in Apache JMeter."
"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."
 

Pricing and Cost Advice

"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."
"We use the open source version."
"The solution is free of cost as it is open source."
"Apache JMeter is a free, open-source solution."
"Apache JMeter is an open-source solution, so it's free to use."
"This is an open-source solution, so there are no licensing costs associated with it."
"This is an open-source solution, so there are no licensing costs involved."
"We didn't pay licensing fees for Apache JMeter because it's an open-source tool. We only paid for the machines where we installed Apache JMeter modules."
"It is much cheaper than Micro Focus LoadRunner. We need perpetual licenses. Support is included in the first sale. After that, you need to renew support every year."
