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.

Has monitoring capabilities integrated into it to see the performance of components while the test is in the running phase
NetStorm can generate high load with a single machine. Its Runlogic feature is very useful to send load to cover each and every flow of the application. NetStorm gives the feasibility of generating load with multiple load arrival models helping components to be tested based on its usage. NetStorm has monitoring capabilities integrated into it to see the performance of components while the test is in the running phase. One more great functionality is the ability to control the load runtime by increasing or decreasing the virtual users or pausing the users to keep on repeating the transactions without exiting.

Quotes from Members

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

Pros

"The solution helps by detecting bottlenecks."
"JMeter's most valuable feature is the RegEx Extractor."
"We find the ease of use and the reports and graphs available valuable."
"JMeter can be integrated with most open-source platforms like Grafana, Prometheus, or even with custom-made tools by extending it and integrating from GitHub."
"The solution is scalable."
"We had some challenges testing HTTP/2 APIs, which are becoming more prevalent with advancements like 5G. So, we added another plugin to help with HTTP/2 API load testing. Apache JMeter, with additional plugins, now supports HTTP/2, which is critical as everyone moves from HTTP/1 to HTTP/2."
"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."
"Apache JMeter is well-known and widely used among developers, particularly on popular developer forums. While it may not have the most user-friendly interface, it offers strong support through official manuals and various articles from companies providing load testing services. The tool is free, has a substantial community, and serves as a fundamental choice for testers, especially those new to performance testing. While other tools like K6 may be more developer-oriented, JMeter's affordability and accessibility make it suitable for those without extensive performance testing experience."
"Designs dynamic scripts and scenarios, as per our requirements, which is one the most important feature available in NetStorm. It helps us to do performance testing of our application in a periodic way."
"NetStorm can generate high load with a single machine. Its Runlogic feature is very useful to send load to cover each and every flow of the application. NetStorm gives the feasibility of generating load with multiple load arrival models helping components to be tested based on its usage."
"This tool helps to focus on real-time transactions that occur at a very high rate."
 

Cons

"From an improvement perspective, consider a scenario where your application needs to retrieve data from PayPal and store it in an Excel file in an external network."
"Apache should have a graphic interface."
"The tool needs to have a better Graphical User Interface. Many of the solution's features are difficult to understand due to the complex user interface and user experience. The product needs to add plugins. It should also work on the integration with external partners like IDE and API gateways."
"The tool should be made a bit more robust, and better support should be made available."
"The initial setup is complex and needs to be upgraded."
"We're like the solution to be more user-friendly."
"The tool needs improvements related to client-side metrics, integrating with tools like YSlow or HTTP Watch, and enhancing mobile testing capabilities."
"Both scalability and stability could be improved in Apache JMeter."
"Need to add or support some more APIs in the Script Manager window."
"The user interface had to be improved for the product. Its user interface should be made simple and easy to customize as per user needs."
"In the next release, we are looking for a JS instrumentation feature that would be helpful in identifying client-side issues at an early stage, or during testing."

"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"
"Apache JMeter is a free tool."
