GUI needs improvement, and it is not easy to learn, it requires upfront learning
Pros and Cons
- "The most valuable feature of this solution is that it is free."
- "In this tool, automation in general is almost non-existent. Everything is done manually."
What is our primary use case?
What is most valuable?
The most valuable feature of this solution is that it is free. If not for that, we would be using a different tool.
What needs improvement?
The graphical user interface could be improved.
In this tool, automation in general is almost non-existent. Everything is done manually. I would advise those who put this together to try to simplify it for their end users, such as being able to automate at their desks. Such as manual relations and social management.
Purely on the feature set, it lacks automation, therefore it requires a lot of manual work.
For how long have I used the solution?
As a performance engineer, I use it almost every day.
I have been using Apache JMeter for two years.

Learn what your peers think about Apache JMeter. Get advice and tips from experienced pros sharing their opinions. Updated: April 2025.
851,604 professionals have used our research since 2012.
What do I think about the stability of the solution?
Apache JMeter seems to be stable enough.
What do I think about the scalability of the solution?
In terms of scalability, we haven't pushed it to a large scale yet.
The majority of users are performance engineers, but there are also some developers.
There are four performance engineers and at least three developers who use JMeter on occasion.
We intend to increase usage, but it is already being used exclusively and extensively.
How are customer service and support?
There is no technical support program for Apache JMeter. There is only an online community of people who help one another.
The community is helpful and fairly advanced.
Which solution did I use previously and why did I switch?
In the past, I used to use various tools, primarily LoadRunner.
When I changed jobs, and the new company only used JMeter because we didn't have a license for LoadRunner, I started working with Apache JMeter.
How was the initial setup?
The initial setup was very easy.
We used it on a desktop computer. It is also used in the cloud. The idea behind using it in the cloud was to spread loads across multiple machines.
What about the implementation team?
We carry out the deployment ourselves.
We have one performance engineering consultant who maintains this solution.
What was our ROI?
That would not be applicable because it is a free solution.
What's my experience with pricing, setup cost, and licensing?
Licensing costs are rare.
There are operational costs related to using Amazon Cloud, but the tool itself.
Which other solutions did I evaluate?
I looked into other options, such as Bluehost, SmartBear, Epic, and LoadRunner but Jmeter proved to be sufficient for our needs.
We chose JMeter based on its pricing structure.
What other advice do I have?
My advice is that it requires a fairly consistent amount of initial learning. It is not simple to learn.
I would rate Apache JMeter a three out of ten.
Which deployment model are you using for this solution?
Private Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

Senior Manager, Performance Engineering at Enel Group
It's a free tool with a vast knowledge base, but the reporting is lackluster, and it has a steep learning curve
Pros and Cons
- "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's reporting is extremely rudimentary. The fundamental reporting mechanisms need to be drastically improved. It doesn't utilize an automatic session management mechanism or methods other tools use like parsing cookies and variables. Everything needs to be done manually. There's no automation."
What is our primary use case?
JMeter is used by a team of four performance engineers. We monitor tasks on the API level, so all of the requests are hitting individually.
How has it helped my organization?
JMeter has helped us streamline our applications by identifying multiple bottlenecks in our systems and exercising tasks against APIs.
What is most valuable?
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.
What needs improvement?
JMeter's reporting is extremely rudimentary. The fundamental reporting mechanisms need to be drastically improved. It doesn't utilize an automatic session management mechanism or methods other tools use like parsing cookies and variables. Everything needs to be done manually. There's no automation.
For how long have I used the solution?
We've been using JMeter for the past three years.
What do I think about the stability of the solution?
JMeter never crashed on us. It's highly stable.
What do I think about the scalability of the solution?
JMeter is highly scalable.
How are customer service and support?
There is no technical support for JMeter.
Which solution did I use previously and why did I switch?
We previously used LoadRunner, but we switched because the organization had an accumulated knowledge of JMeter. Nobody really knew LoadRunner. However, the biggest advantage is that it's free, and we didn't have to invest in acquiring a performance testing solution.
How was the initial setup?
JMeter is simple to install. We did it in-house, and it takes a day or two to deploy it to the cloud. There's no maintenance required.
Which other solutions did I evaluate?
We looked at a number of different tools.
What other advice do I have?
I rate JMeter five out of 10. You need knowledgeable employees to work with the tool because it's difficult to learn. There is a steep learning curve, so you shouldn't expect an entry-level engineer to pick up the tool quickly and become proficient. It takes a considerable amount of time.
Which deployment model are you using for this solution?
On-premises

Senior Cloud Performance Engineer at Oracle
Allows us to create scripts and is useful for load testing and performance testing but could be more stable
Pros and Cons
- "It is scalable. You can scale up to 1,000 users in JMeter. If you can put up four slave servers, you can easily ramp up to 1,000 users."
- "JMeter should be more stable. Every time there is a new release coming up, a lot of its older functionalities or the new functionalities that are brought in are not very well-documented. It should be documented properly, and there should be proper use cases."
What is our primary use case?
We use this solution mostly for creating scripts, load testing, and performance testing. If my client doesn't have a tool or I don't have a tool, I try to leverage JMeter because it's an open-source tool.
I personally use JMeter for things which cannot be covered by our load testing tool, which is OATS, Oracle Application Testing Suite. This is a tool that was developed by Oracle but is no longer in use because Oracle has stopped developing it.
The solution is deployed on-prem and on private and public clouds.
What needs improvement?
JMeter should be more stable. Every time there is a new release coming up, a lot of its older functionalities or the new functionalities that are brought in are not very well-documented. It should be documented properly, and there should be proper use cases. A lot of the newer features don't work, and sometimes you have to spend a lot of time maintaining the scripts. That is something JMeter could probably look at.
For example, in JMeter 5 they brought in a lot of new controllers. But there isn't a lot of documentation available on the Apache site on how you're supposed to use those controllers. They've explained the controller functionality, but there aren't any proper use cases to show that.
For how long have I used the solution?
I have been using JMeter for a long time and do a lot of work with this solution.
What do I think about the stability of the solution?
It's not stable. With every new release, they come up with newer features, which aren't always very stable. So, stability is a concern.
What do I think about the scalability of the solution?
It is scalable. You can scale up to 1,000 users in JMeter. If you can put up four slave servers, you can easily ramp up to 1,000 users. That's not a problem.
Because it's open-source, a lot of organizations try to leverage JMeter into everything. I don't think JMeter is currently very adaptable to all the technologies. That is something Apache should think of – incorporating other technologies and other tech stacks, which can be scripted from JMeter and tested using JMeter.
How are customer service and support?
On a scale of 1 to 5, I would rate technical support 2.5
They're not very good because JMeter is an open-source tool. You can raise a bug to JMeter, and they might fix it or they might say that, "We will actually fix this in the next release." So, because it's an open-source tool, you do not get dedicated support. You have to raise tickets and wait. If you use BlazeMeter, the support is probably a little better because you can take your issues there.
I don't think support is great if you compare it with tools like NeoLoad or LoadRunner where they have a dedicated support team. You can raise tickets. You have a direct conversation with their engineers. They can help you understand where the issue is exactly. That kind of support is not in JMeter, at least not now. BlazeMeter has it, but I have not used BlazeMeter support, so I'm not sure how it is. But from what I have seen with JMeter, support is not great.
How was the initial setup?
It is straightforward, but for JMeter 5, since they have introduced SSL handshake at the slave level, that becomes a little bit of a challenge for somebody who is doing it for the first time if you're doing a distributed execution, that becomes a challenge.
But since there was not enough documentation, I had to do a lot of troubleshooting on my own, since it was new. Now there's a lot of documentation available, but initially, there was not much documentation.
JMeter is pretty easy to use if you are using it for the purpose of only developing scripts. You can just uninstall the file and you can start using it. The only challenge happens if you're trying to access the internet over any kind of proxy. Then, you'll have to start it via the proxy mode.
Otherwise, deploying JMeter is pretty easy compared to other tools. You just have to download, unzip, and you are ready to go.
What about the implementation team?
We installed JMeter ourselves.
What other advice do I have?
I would rate this solution 7 out of 10.
Which deployment model are you using for this solution?
Hybrid Cloud

We can sale it to the extent we need but scripting concepts needs improvement
Pros and Cons
- "It is scalable. It is cloud-based."
- "There is room for improvement in the scripting concepts. The scripting and even the results and reports were very elaborative and informative in LoadRunner, but not in JMeter because everything has to be done manually."
How has it helped my organization?
What needs improvement?
There is room for improvement in the scripting concepts. The scripting and even the results and reports were very elaborative and informative in LoadRunner, but not in JMeter because everything has to be done manually.
And, whichever metric we need, we need to add it manually and start monitoring it, but not in LoadRunner. It was a very elaborate report. A lot more information, but not in JMeter.
For how long have I used the solution?
I have been using it for four to five months. I have been with the organization for just four to five months.
What do I think about the scalability of the solution?
It is scalable. It is cloud-based. Whenever, based on the requirements, we can scale it to whatever extent we need. But with respect to LoadRunner and NeoLoad, since they are all paid ones, we had to follow a procedure even if we had to scale for certain protocols or with respect to users. We had to pay the cost.
There are around seven to eight members using this tool.
Which solution did I use previously and why did I switch?
I have switched over to a new company where they used JMeter. Earlier, we used Micro Focus LoadRunner.
More than NeoLoad, I prefer LoadRunner the most because I have had experience from the past 13 to 14 years, majorly on LoadRunner.
Any of the customers would be very easily convinced with the LoadRunner or the NeoLoad reports more than the JMeter reports. And even interpretation of the results, everything would be very much comfortable and customer-friendly with respect to LoadRunner and the other tools, but not with JMeter.
If I had to compare with respect to JMeter and other tools, the script creation, user-friendliness, handling of the tools, customization of scripts - everything is very much easy. Even for training, it would be very easy with LoadRunner more than JMeter.
And documentation, materials, support, technical support, installation, everything - whatever the support- also looks pretty good in LoadRunner or NeoLoad, not in JMeter. Since it's open source, everything has to be done on your own. And the training of freshers and juniors would be more comfortable with LoadRunner than JMeter.
What's my experience with pricing, setup cost, and licensing?
It is free.
Which other solutions did I evaluate?
What other advice do I have?
I propose they use Micro Focus LoadRunner or NeoLoad. I have even put forward the proposal here [in my current company] as well.
Overall, I would rate it a six out of ten.

Lightweight, simulates applications, and creates threads with good server utilization, but scalability and stability both need improvement
Pros and Cons
- "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."
- "Both scalability and stability could be improved in Apache JMeter."
What is our primary use case?
We have a Neotys slave server configuration where we have one server that caters to three servers, and we test most of the load on Apache JMeter, particularly for a hundred users. We test the load for web applications, services, and the rest of the APIs, though our current setup for Apache JMeter isn't that big.
How has it helped my organization?
Initially, Apache JMeter had a complex configuration; its UI was tricky and required a lot of resources. Creating scripts and running tests on Apache JMeter was always confusing, but nowadays, with more documentation and UI enhancements, Apache JMeter has improved. Previously, recording and creating scripts was tricky, and you had to do it manually. Now there's a recording facility in Apache JMeter that lets you create and modify scripts and test faster, which helped improve my organization.
What is most valuable?
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.
What needs improvement?
Both scalability and stability could be improved in Apache JMeter.
What I'd like to see in Apache JMeter in the future is ease of use in terms of scripting. A recording capability similar to what LoadRunner offers, where you can record scripts, make some modifications, then the script will be ready, is another advanced feature I'd like Apache JMeter to have. The two features would make it easier for new users to learn how to use Apache JMeter and help users utilize the tool more quickly.
For how long have I used the solution?
I've been using Apache JMeter for more than six or seven years.
What do I think about the stability of the solution?
Apache JMeter isn't as stable because it sometimes crashes when you're running a test. The performance of Apache JMeter could be improved because testing on it isn't always as smooth sailing.
The tool is partially stable. You can't expect Apache JMeter to run well for enterprise-level, high-load applications. It's a good tool for more straightforward or lightweight web applications but not for CRM-type applications.
What do I think about the scalability of the solution?
Scalability-wise, Apache JMeter could be improved because if you try to implement it on multi-servers, the threads running on the tool don't hold up well.
Which solution did I use previously and why did I switch?
We used LoadRunner before using Apache JMeter. As Apache JMeter is open source, and we only needed to test lightweight applications, we were pretty sure we wanted to go with Apache JMeter.
How was the initial setup?
Apache JMeter is an open-source tool that you can install directly from the web with binary files, so setting it up on one to two machines is easy. The setup could be tricky if you hook Apache JMeter to three or more different machines, and it's also tricky when you execute it after.
What about the implementation team?
We implemented Apache JMeter in-house.
What was our ROI?
I've seen ROI from Apache JMeter, mainly because it doesn't cost much to maintain, and we can use it on a few lightweight applications.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
I have experience with Apache JMeter, with version 5.5. as the most recent version I've used.
Apache JMeter is deployed on-premises, but my company did a POC with Apache JMeter and BlazeMeter. BlazeMeter is a CA proprietor tool where you can hook up Apache JMeter scripts. BlazeMeter is a cloud-based tool where you can run tests with the help of Apache JMeter scripts.
At the moment, only two people use Apache JMeter within my company. Two people can handle the deployment of Apache JMeter, while only one person is required to maintain it.
My advice to people looking into implementing Apache JMeter is to make the decision based on the application portfolio. For example, if it's more diverse, then using Apache JMeter could be tricky, but if you're only testing lightweight applications, Apache JMeter will be a viable solution.
Apache JMeter requires minimal investment, yet it has some returns, and it's a good tool, so I'm rating it as seven out of ten.
Which deployment model are you using for this solution?
On-premises

An open-source tool that's easy to set up and customize
Pros and Cons
- "The solution is scalable."
- "Until now, JMeter is not supporting most of the protocols."
What is our primary use case?
We have a couple of applications in banking.
What is most valuable?
It's an open-source tool, Apache JMeter.
It's easy to customize. Customization depends on the requirements, however. It provides an enormous amount of plugins. Based on the customer requirements, we can customize our code and we can go out and execute the test. JMeter integrates well with Jenkins. The cloud offers CI/CD activity.
The solution is scalable.
The stability is good.
Its initial setup is very easy.
There is good documentation available.
What needs improvement?
Until now, JMeter is not supporting most of the protocols. It's widely using web HTTP and a few other protocols as well, however, it's not supporting the SAP or Citrix ones. Protocol-wise, the JMeter needs to improve.
Recently, there was a Log4j error. They have since mitigated that, in JMeter, for the free version. The security concern was handled quite well compared to the previous versions.
For how long have I used the solution?
I've been dealing with the solution for more than five years.
What do I think about the stability of the solution?
The solution has been stable. There are no bugs or glitches. It doesn't crash or freeze. It's reliable.
What do I think about the scalability of the solution?
It's scalable. We have very good load balancing or load distribution. It will be very easy for us to add multiple machines and make whatever we need. However much we want, we can scale.
How was the initial setup?
It is very easy to set up. It's not overly complex or difficult.
What's my experience with pricing, setup cost, and licensing?
The solution does offer a free version.
What other advice do I have?
I'd rate the solution eight out of ten.

Leveraging advanced sampling and controllers for effective performance testing
Pros and Cons
- "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."
- "It requires integration with other tools for live metrics, which is time-consuming."
What is our primary use case?
I use Apache JMeter primarily for performance testing projects. It is a day-in, day-out tool where we run performance test executions to create a production-like load on systems. We analyze the results and share recommendations with customers. We use it for load testing, stress testing, and endurance testing on systems.
How has it helped my organization?
Apache JMeter helps us meet our requirements for performance testing by allowing us to create scripts and run them. It is part of our daily routine, and it provides us the capability to test using different protocols like gRPC, which is essential for our operations.
What is most valuable?
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. These features meet our requirements and allow us to effectively create and run our performance testing scripts.
What needs improvement?
Apache JMeter has room for improvement in handling larger infrastructures as it consumes a lot of CPU and memory. It requires integration with other tools for live metrics, which is time-consuming.
Also, the failure response times are calculated in the overall response time analysis, which should be separate. Better script maintenance and integration with ALM or repository tools would be beneficial.
For how long have I used the solution?
I have been using Apache JMeter for about 14 years.
What do I think about the stability of the solution?
Apache JMeter is generally stable, with a high stability rating of nine out of ten. Any instability could impact timelines, project deadlines, releases, and revenues.
What do I think about the scalability of the solution?
While Apache JMeter can scale to the required number of user loads, it requires a lot of manual work and larger infrastructure, which are challenges to its scalability.
How are customer service and support?
There is no dedicated support team for Apache JMeter as it is an open-source tool. We rely on community support, which is not enough and needs to be improved.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I previously used LoadRunner. We switched due to customer preference for a commercial tool.
How was the initial setup?
The initial setup of Apache JMeter is rated between eight and nine out of ten. If you have knowledge, it's an easy setup.
What about the implementation team?
No specific team is required to maintain Apache JMeter. Performance test engineers familiar with the tool can maintain it.
What's my experience with pricing, setup cost, and licensing?
Apache JMeter is an open-source tool, so there are no costs associated with its setup, pricing, or licensing.
Which other solutions did I evaluate?
We evaluated NeoLoad and found LoadRunner to be more realistic than NeoLoad and Apache JMeter.
What other advice do I have?
For those looking into open source, JMeter is an excellent tool and should be the first option. For commercial needs, BlazeMeter is a good choice, or LoadRunner is a good choice for a commercial setup.
I'd rate the solution ten out of ten.
Which deployment model are you using for this solution?

An open-source tool that is easy to use and can be integrated with multiple solutions
Pros and Cons
- "It is an open-source tool that is easy to use. It can be easily integrated with multiple tools, including Selenium."
- "The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."
What is our primary use case?
Load testing is something that we used to do on Apache JMeter. We have regular releases every two weeks with varying features and modules. For major releases, where most of the EPS are modified or new features are introduced with new pages, we perform a performance test once every three to four months. We have a fixed schedule for performance testing before the sale, such as Thanksgiving and Black Friday, to ensure stability and performance during the sales period.
What is most valuable?
It is an open-source tool that is easy to use. It can be easily integrated with multiple tools, including Selenium. The tool also provides a recording and playback feature, along with the ability for modification and parameterization. Since it is an open-source tool, it can be easily integrated with many other tools, such as BlazeMeter, making the integration process very helpful.
What needs improvement?
The UI of the solution needs to be better. The UI takes up a lot of our bandwidth. So, we always run on the command line. Hence, improving the UI is needed. If it can be more lightweight, the editing can also be made easier.
For how long have I used the solution?
I have been using Apache JMeter for four to five years.
What do I think about the stability of the solution?
Apache JMeter is a stable tool. Around 10,000-12,000 users are using the tool. One can increase its usage, but we haven't done so since we will need multiple machines to be connected to a network to generate the load. So, we haven't exceeded its use beyond 10,000 users.
What do I think about the scalability of the solution?
Apache JMeter is a scalable tool.
How are customer service and support?
We haven't used the solution's technical support.
Which solution did I use previously and why did I switch?
We used other solutions in the past, but they were costly since they require a license, whereas Apache JMeter is free. Hence, we prefer Apace JMeter.
How was the initial setup?
The solution's initial setup process was straightforward since setup can be done by opening a JAR file. It can be deployed in half an hour. Experienced people can deploy it in 15-20 mins, and newer ones may take up to an hour.
Also, we don't deploy on any server. Normally, the tests are on local ones.
For deployment and maintenance, you need knowledge of scripting and APIs. But otherwise, maintenance should be easy. Once you record and have the script ready, until and unless there are modifications to the application, maintaining it should not be much hassle.
What about the implementation team?
The implementation was done in-house.
What was our ROI?
There is no investment as such. Only the resourcing part is there in the tool.
What's my experience with pricing, setup cost, and licensing?
Apache JMeter is a free tool.
What other advice do I have?
I recommend Apache JMeter to others who want to use it. I rate the overall solution an eight out of ten.
Which deployment model are you using for this solution?
