"It's very useful for performance and load testing."
"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."

Room for Improvement

Apache JMeter faces challenges with its user interface, making it less intuitive. It struggles with handling high loads and resource consumption. Reporting functionalities need enhancement for better visual representation and ease of use. Integration and scalability require improvements, and automation is limited. Support for various protocols and scripting languages is lacking. Documentation and user guidance are inadequate, which complicates user onboarding. Enhancements in memory management and graphical features are also needed to improve usability.

"Documentation is not comprehensive, making it difficult to find the right answers."
"Some features still require a certain knowledge level to use effectively, and making these features more user-friendly would be beneficial."
"It requires integration with other tools for live metrics, which is time-consuming."

ROI

Apache JMeter is scalable and integrates easily into CICD processes, offering significant reductions in licensing costs. Users experience good results when conducting frequent performance testing for high user volumes. Compared to HP Performance Center, the return is significantly higher with five times less investment. Despite being a free tool, it incurs minimal maintenance costs, making it ideal for lightweight apps. Licensing is not a concern since clients cover costs when using services like Microsoft Azure.

Pricing

Apache JMeter is widely recognized as a free, open-source tool with no licensing costs, offering cost-effective performance testing solutions. Users appreciate its lack of fees, making it an attractive option for enterprises needing economical testing tools. Although JMeter meets basic needs, some organizations may opt for additional support or advanced capabilities through integrations like BlazeMeter, which incur some costs. Organizations often use their own infrastructure, minimizing additional expenses related to setup and support.

"It is free."
"The tool is open-source."
"Since it's free, there's no need for extensive support or improvements in pricing."

Popular Use Cases

Users primarily utilize Apache JMeter for performance and load testing across various applications, including websites and APIs. It enables testing of throughput, response times, and resource utilization. They often integrate it with CI/CD pipelines, handle concurrent user loads, and simulate user interactions. JMeter is widely used for stress, endurance, and capacity testing in diverse environments, leveraging its cost-effectiveness and adaptability to both cloud and on-premise deployments for comprehensive performance assessments.

Service and Support

Apache JMeter, being open source, lacks official customer service or technical support. Users rely heavily on a large, vibrant community for assistance. While responses are generally prompt and helpful, some find the non-existence of dedicated support challenging compared to commercial tools. Extensive online resources, forums, and documentation are available. Users appreciate community support but also highlight limitations in comparison to paid alternatives.

Deployment

The initial setup of Apache JMeter is generally straightforward and easy when following available documentation. Many users find it quick, often completing it in under an hour, though technical knowledge can affect ease. Some encountered complexity when dealing with distributed setups or specific configurations. While simple for those with experience, newcomers may need guidance and resources like blogs or instructional videos. Apache JMeter's basic deployment requires minimal installation effort, typically just downloading and extracting the necessary files.

Scalability

Apache JMeter exhibits moderate scalability with a master/slave architecture available to increase user loads. It is generally expandable, but some users note memory limitations at higher capacities. To achieve substantial scaling, users often configure distributed testing across multiple machines or use cloud-based options like BlazeMeter. While capable for midsize loads, intense configurations for large user numbers are necessary. Users typically find its scalability satisfactory but not as seamless as other paid tools.

Stability

Apache JMeter demonstrates considerable stability but faces challenges with high loads and multiple users. Tests indicate the need for sufficient memory and resource allocation, with some instability noticed when handling large-scale testing. Users frequently rate its stability between seven to nine out of ten, acknowledging occasional crashes or bugs. Experienced users report stable performance, while beginners may encounter difficulty. Despite some issues, it remains reliable for most scenarios.

These insights are based on the in-depth reviews provided by peers to help you make a better buying decision.

How does JMeter work?

JMeter sends requests to a target server by simulating a group of user requests. Then it collects and calculates statistics on the performance of the target. This target can be a server or an application.

You can test the performance of static resources, such as JavaScript or HTML, and dynamic resources, such as JSP, Servlets, and AJAX. It is also helpful to determine how many concurrent users your website can handle.

There are two main tests you can carry out with JMeter: load test and stress test. The load test models expected usage of a server by simulating multiple users accessing the web server simultaneously. The stress testing aims to find the maximum load capacity of the server or application.

Apache JMeter Key Features

JMeter enables fast test plan recording, building, and debugging via a featured test IDE (integrated development environment).
Command-line mode allows carrying out load tests from any OS compatible with Java.
JMeter can extract data from most popular response formats, such as HTML, JSON, XML.
JMeter is entirely portable.
A multithreading framework allows you to simultaneously test multiple samplings and separate thread groups.
Thanks to the caching feature, you can conduct offline analysis or replay test results.

Apache JMeter Benefits

Reviews from Real Users

Stephen B., I.T. Architect, Analyst, and Developer at an educational organization, says, "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."

"I like the fact that JMeter integrates well with other tools," adds the Founder and Principal Consultant at a tech services company.

A Quality Engineering Delivery Leader at a financial services firm says, “The performance of the solution is excellent. They have designed the product so that it is very easy to configure. You can basically do anything you like with the product. It's not very restrictive. We like the fact that the technology is open-source.”
