Have built custom performance test scripts and integrated them into automated pipelines seamlessly

Apache JMeter has its own pros and cons when compared to other tools. It is easy to use the tool and it has open-source capability so we can build our custom scripts and execute them. It provides other capabilities, such as integrating a database and connecting to other application servers for monitoring and related functions. We use dynamic HTML reporting, which helps us in testing analysis by pinpointing the bottlenecks based on the reports. We can identify the specific areas that need attention, troubleshoot them, and report to the development team. The user-friendly GUI for creating and managing tests makes it very easy to drag and drop samplers. For example, if you want the HTTP sampler, you can drag and drop it and use it. For configurations, we have other samplers. For results, we have the view results samplers that we can also drag and drop. The UI is good in comparison with other tools. Regarding integration with CI/CD pipelines, we can create Apache JMeter scripts and use the Docker image. From the image, whatever scripting we have done can be connected. We can use the CI/CD pipelines and connect them with Jenkins tools and GitHub. Then we can create the pipelines and automate the end-to-end flow. For connecting Jenkins to Apache JMeter, JMeter plugins are available, and we have used them. Apache JMeter also has some third-party plugins, which are not native samplers. If we want to use custom test executions, we definitely use all the different plugins available in Apache JMeter. The capability to simulate users has impacted testing resources and outcomes as Apache JMeter is based on Java, which has a limit to the users in a particular load generator. Apache JMeter provides distributed load testing where you can connect multiple PCs in a master and slave concept, allowing you to pump the load with any number of users. In the past, I have done load testing with 10,000 users by connecting the Apache JMeter distributed network in BlazeMeter. There is a cloud version available, the updated BlazeMeter, and I used that. It is very easy to launch load generators in BlazeMeter, and then we can run the test, scaling up beyond 10,000 users.

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

"Scripting with the solution is good."

"We are using this for performance testing and some automation."

"It is scalable. It is cloud-based."

"It's an open-source tool, Apache JMeter, it's easy to customize and it provides an enormous amount of plugins, so based on the customer requirements we can customize our code and execute the test, and JMeter integrates well with Jenkins while the cloud offers CI/CD activity."

"The reports and analysis tools are very good. They are the solution's most valuable features."

"The solution offers a lot of plug-ins and a huge, continuously developing community that is regularly offering new features and plug-ins."

"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."

"Very easy to download and setup the entire infrastructure (Controller + LGs)."

More Apache JMeter pros

"It has improved our visibility of reporting and simplifying performance testing for larger projects/programs."

"Less coding is needed, it is easy to understand, and it is easy to integrate with existing systems so I can test more than one performance test type, including load testing, stress testing, and scalability testing."

"Rational Performance Tester was perfectly suited to provide the means to monitor the availability and performance of our web services."

"This tool is very scalable, and for large scale tests, i.e., 5000 virtual users and up, it performs very well."

"The setup was straightforward, it depends on the company's regulations and infrastructure policies."

"ROI is big because we do not need vendors to assist some with performance testing."

"Technical support is very good. I'm very satisfied with the assistance we've received so far."

"Customization and extensions made in Java is valuable because this can help you set elements to improve your results."

More IBM Rational Performance Tester pros

Cons

"The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."

"Considering the kinds of tests we are performing here, where we launch several tests at the same time as a batch request, JMeter is not the best tool for the job. Those kinds of things could be done easily with other tools, like T6."

"The installation needs some work. It could be simplified."

"There could be improvements in terms of memory utilization. We are going to migrate away from JMeter in the near future."

"In this tool, automation in general is almost non-existent. Everything is done manually."

"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."

"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."

"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 really clean at this point."

More Apache JMeter cons

"Support for more protocols is required."

"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."

"Since it is Java-based, it is expected to be a resource eater on Windows."

"There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester."

"Reporting needs improvement to provide more customization options in the performance test analyst to build custom reports."

"For a rational performance testing solution, the initial setup is very complex. The setup was difficult and the documentation was not very up to date."

"It is complex for a novice."

"It was complex."

Pricing and Cost Advice

"Apache JMeter is a free tool."

"This is an open-source solution, so there are no licensing costs involved."

"Since we are using an outsourced solution, it is not paid for by our company."

"Apache JMeter is an open-source solution, so it's free to use."

"I switched to Apache because it is free. Other tools are much too expensive and can cost up to $50,000 a year if you are looking at commercial options."

"This is an open-source solution, and there are no fees."

"We use the open source version."

"JMeter is open source, so there are no licensing costs associated with it."

More Apache JMeter pricing and cost advice

"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."
