Executive SummaryUpdated on Jan 6, 2025

Apache JMeter and ReadyAPI Performance are tools competing in the performance testing category. JMeter seems to have the upper hand due to its open-source nature and community support, making it cost-effective compared to ReadyAPI's fee-based model.

Features: Apache JMeter is favored for its open-source nature, flexibility, and wide array of plugins, making it cost-effective for performance testing. It supports load testing across various protocols and integrates well with CI/CD pipelines. ReadyAPI Performance offers comprehensive API testing with robust reporting and automation capabilities, providing ease of use for complex testing scenarios but at a cost.

Room for Improvement: Apache JMeter lacks in GUI performance, often becoming unresponsive under large loads, and presents issues in reporting and configuration. Its reliance on community support instead of dedicated technical support is also a downside. ReadyAPI Performance is criticized for its cost and lack of a free tier suitable for students or small operations despite being robust.

Ease of Deployment and Customer Service: Apache JMeter offers diverse deployment options including on-premises and hybrid cloud environments, supported by strong community resources but lacking official support. ReadyAPI Performance targets on-premises and public cloud setups, providing established customer service, though it comes at a cost, contrasting JMeter’s free community-driven support model.

Pricing and ROI: Apache JMeter, as an open-source tool, incurs no licensing costs, making it attractive for budget-conscious organizations, with a competitive ROI especially for limited scaling. ReadyAPI Performance involves tiered pricing with licensing fees, which some users find justified by its advanced features, but it might not be economical for small operations or educational purposes.

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.

Open-source and flexible but needs client-side scripting

It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS. Also, the APIs tested with SoapUI can be directly used, avoiding the need to create collections like in Postman. The client-side scripting, if incorporated, would provide a complete solution for performance tests. It can handle user distribution and transaction throughput distribution effectively.

Quotes from Members

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

Pros

"We have found this solution to be a stable and reliable tool."

"The most valuable feature in JMeter is the Thread Group, which helps us to see whether the performance is good."

"We appreciate that the solution is free to use, as an open-source tool."

"They can easily view the results and gain valuable insights."

"JMeter is a free tool with a large user population, which comes in handy because we have a vast knowledge base to tap into when needed. It's also easier to hire consultants who know JMeter."

"JMeter is easy to use for a user who doesn't have too much knowledge of programming or certain languages."

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

"User-friendly and open source."

More Apache JMeter pros

"It has helped improve productivity and functionality."

"It's like a centralized interface that allows us to increase the quality of our APIs."

"It is a very good and handy product, there are so many features, and it is getting more popular day by day."

"It stores good reports, as in, improved reports if compared with the SoapUI. It also has in-built security. You just need to switch and check the security testing. My team has never used it, but I know ReadyAPI provides those facilities as well."

"he initial deployment process is easy."

"It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS."

"We can scale."

"Eventually, we enhanced the whole automation, and how it should get integrated with the hardware, or another tool like Jenkins for CI/CD automation."

Cons

"Documentation is not comprehensive, making it difficult to find the right answers."

"If you go above the 200 user mark, the application creates a bottleneck and that's one of its major drawbacks."

"If the solution was GUI based, I believe that it would be more versatile."

"Currently, the integration pipeline is implemented by using Jenkins or a similar tool platform. These are continuous integration tools. As far as I know, integration is done by using custom scripts. It would be good if the integration with a continuous integration pipeline, like Jenkins or Hudson, can be done out of the box without using a script."

"Apache JMeter may have difficulty recognizing dynamic objects in some critical cases, which can lead to challenges in terms of object identification."

"The solution could use some sort of educational features to offer tips and hints to help users navigate it better. They should improve the manuals and help files."

"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."

"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."

More Apache JMeter cons

"This is an area for improvement with the tool. We unnecessarily use JMeter for some website testing, which we would like to avoid by introducing this tool for API and load testing because it provides load testing features."

"We need some time to understand and configure the solution."

"The solution’s interface could be improved."

"It is very slow sometimes. If they could improve its performance, it would be really great for the users."

"I want the solution to be able to monitor Apache Kafka activity as well."

"This solution could be improved by offering artificial AI testing in addition to API testing. For example, we would like to have machine learning testing because when test applications, manual work could be completed automatically using this functionality."

"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."

"It is very slow sometimes."

Pricing and Cost Advice

"No licensing is required as it is a free, open-source tool."

"We use the open source version."

"The product has reasonable pricing."

"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."

"The solution is free of cost as it is open source."

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

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

"JMeter is open source and available free of charge."

More Apache JMeter pricing and cost advice
