TusharShankar - PeerSpot reviewer
QA Manager at Synechron
Performance testing has become central and reporting has provided clear insights for our teams
We do have command prompt related or CLI functionality with Apache JMeter, so it is easier. However, since it is open source, much work has not been put into the GUI part. The GUI could definitely be enhanced. One drawback which I can see when I compare it with other tools is the amount of cache that it uses, the memory that it uses. It becomes very difficult to work with when we have a lot of requests that need to be processed. Anything more than 10,000 requests becomes a bit of an unfavorable task when using Apache JMeter altogether. Otherwise, it does help anyone who is starting off with performance testing.

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

"They can easily view the results and gain valuable insights."
"I appreciate JMeter's simplicity and power for performance testing."
"To me, what's most valuable in Apache JMeter is that it's a lightweight tool for application testing. It's the best load-testing tool for my company because Apache JMeter simulates your application during testing. Apache JMeter also creates threads with good server utilization. Apache JMeter allows you to focus on analyzing the situation, looking into measurements, response time, and client-server responses, which I find valuable."
"From the customers' perspective, the most valuable feature is the price."
"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."
"The solution is free, so you don't need to worry about licensing costs."
"I use all the tools, but one feature that stands out is JMeter's ability to test when services are sending a particular kind of request. We are using specific ports to send queries, and assess the performance based on the time it takes these queries to respond. You can use it with stuff other than the web performance."
"It's a powerful tool that is open source."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"he initial deployment process is easy."
"It is a very good and handy product, there are so many features, and it is getting more popular day by day."
"The performance and reporting of this solution have been its most valuable features."
"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."
"ReadyAPI automation can help us validate the functionality of most web services, allowing us to find out the exact number of defects before deployment to the user interface."
"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."
"We find the product to be scalable."
 

Cons

"I have not seen a return on investment right now, as there is no improvement in Apache JMeter and reduction in cost, but I save time and reduce costs with Apache JMeter."
"JMeter is probably good for lower loads. It is not comparable to LoadRunner when it comes to higher loads."
"The plug-ins make the reports heavy and they have to be run in non-GUI mode."
"The user interface could be improved."
"The solution needs more metrics for reporting."
"The reports in Apache JMeter could improve."
"There are issues when tests are stopped with large number of concurrent users. Test is not stopped as expected."
"You can't rely on the support."
"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."
"The solution’s interface could be improved."
"I'd not sure if they have the same level of documentation for performance and security testing."
"It is very slow sometimes. If they could improve its performance, it would be really great for the users."
"We need some time to understand and configure the solution."
"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."
"It is very slow sometimes."
"I want the solution to be able to monitor Apache Kafka activity as well."
 

Pricing and Cost Advice

"We are using the free version, and if required, we can easily switch to the other version."
"JMeter is open source and available free of charge."
"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."
"This is an open-source solution, so there are no licensing costs involved."
"Apache JMeter is a free tool."
"When comparing the price with Load Runner, and if the cost is an issue then JMeter is a better choice"
"The solution is open-source."
"Apache JMeter is a free, open-source solution."
"This solution operates on a licence basis and the usage and cost varies according to the use case. It is more expensive if you include access to the learning center. On average it costs approximately 800 Euros."
"We find the cost to be affordable."
"ReadyAPI Performance’s pricing is reasonable."
