Powerful performance testing tool
Apache Jmeter scripts are great for load testing. I like the parameterization strategy offered by JMeter because I can better reproduce real-life scenarios by introducing variables and randomizing my tests. Also, JMeter extensions are accessible in the open-source sector to extend current JMeter capabilities. I love this to do my performance testing.
- User interface is not complex. Easy to understand and work flow is very simple.
- It comes with many useful testing features.
- It's very difficult to find any cons about this powerful tool. Actually it works perfectly for me.
- While installation is very simple, some problems may occur if it is not installed by someone with experience.

Performance is a key and JMeter is a solution
JMeter is being used by our QA teams mainly for performance testing. We are into banking and finance domain. Hence, the performance of the bank transactions should be very rich. JMeter helps us to find bottlenecks around performance issues within our web apps and web services. JMeter also helps us to simulate different user loads in order to test web application under various load patterns.
- Jmeter is an open source and highly customized tool for your needs. There are open source JMeter plugins also available in the market to extend JMeter existing functionality.
- JMeter provides a very easy user interface and pluggable components, and different visual charts and summary report listeners. Also nowadays JMeter supports quite rich HTML reporting.
- JMeter can be used for volume testing, load testing, availability testing. Also, it allows the master and slave concept. Hence you can create multiple load generators and controllers, and JMeter will give you combined execution status.
- JMeter provides great documentation.
- To get a summarized HTML report, the user needs to configure a lot of things. It should be done with a single click like other paid tools in the market.
- Support to measure desktop based application performance.

Most of our developers use JMeter for performance testing. It's a great tool where you can do all kinds of performance testing tests like Baseline test, smoke test, load test, and stress test. It is useful for test performance and scalability of REST APIs. It is used as an automation tool for API testing.
- Automation tool which is best suited to do performance testing
- Easy to use and setup. The software has community and documentation to solve questions.
- Great tool for testing REST APIs
- It should support more test cases running at the same time
- Should be able to support multiple threads for different testing scenarios
- The newer version doesn't have a start time and end time for the test

JMeter, a tool to test web apps
JMeter is being used to run load tests against the web applications that we are working on.
- It allows excluding css and js files from request whenever you want
- The installation is quite simple
- No programming knowledge is required
- I'd like to have the chance to modify the scripts but since they are really big XML file that task is almost impossible
- A friendly UI would be appreciated
Jmeter is used by the development team for testing the performance of web APIs.
- It is very helpful while ensuring performance and stability of web applications
- Good knowledge of programing provides great flexibility to do different things
- You don't need to pay as Jmeter is an open source tool with support from web community
- Recording of tests is very complex for a user with less programming skills.

JMeter, well done taking on the competition
We used JMeter to execute performance tests on our web services. The main business purpose was to assure that changes did not affect web service performance.
- JMeter allows direct interaction with services bypassing the UI which is a main pain point when testing backend systems.
- JMeter has an easy to follow record/enhance/replay mechanism that help create powerful tests in very little time.
- I like the parameterization approach in JMeter as I can better replicate real world scenarios by introducing parameters and randomisation into my tests
- I would like to see a real executable of JMeter instead of using a JAR file. Some companies I worked for had very strict security policies that made it difficult to run JMeter remotely.

Test cloud-based applications with Apache JMeter
We are doing test cloud-based applications with Apache JMeter. This is used only by my team and not across the organization.
- Extending functional JMeter scripts for reliability testing.
- Using the Module Controller to modularize reusable fragments.
- JMeter's capabilities as a testing tool for RESTful APIs.
- I think JMeter hangs up on large loads. I have seen JMeter becoming unresponsive in the middle of a test. It is because of garbage collection in JMeter. We use best practices to mute all listeners, use non GUI mode, etc., but even with many best practices JMeter pauses in between load tests.
- The reporting feature can be improved to provide better test results.

JMeter is a great all around load test tool with some caveats.
We currently use JMeter at one of our divisions in the organization to assess site/system performance, fixing any issues that arise and looking for regressions in performance. We do this on a yearly basis before our holiday peak comes. Although strategically, our test framework/tools team is standardizing the entire company to use another open source tool going forward called Gatling. But we have yet to complete full migration to it, so in the meantime we still use JMeter.
JMeter was selected initially when we started formalizing load testing at my division and was evaluated along with another tool called WebLoad. We picked JMeter for its ease of use, usefulness, and being open source which saved us licensing costs. We primarily use JMeter to generate HTTP requests against our websites, either simulating browser activity or making back end REST API calls.

We picked JMeter for its ease of use, usefulness, and being open source which saved us licensing costs. We primarily use JMeter to generate HTTP requests against our websites, either simulating browser activity or making back end REST API calls.
- Easy of use - in generate load like HTTP requests, and processing/analyzing the responses. No coding is necessary at the basic level, just need to understand load testing and the infrastructure being tested.
- Automatic management of things like cookies to help with session state support - so you don't specifically have to worry about it or handle it
- Lots of testing/configuration options to suit your needs in making the right load generation (sampling requests), and analyzing the results, including any pre and post processing of the results first. Things like the Beanshell/BSF pre/post processors, response assertion, regular expression extractor, XPath extractor, CSV data set config
- There is a JMeter cloud service called BlazeMeter that I think would be useful for those that need to scale up high load without provisioning their own systems. I've not personally tried it though, but I recently attended a meetup presentation that highlighted nice useful features that BlazeMeter provides. One should evaluate the service if they are considering JMeter and need to expand beyond existing hardware resources.
- Programmatic customization - for more lower level detailed programming fine tune control of load test actions and processing of results, one has to write a JMeter plugin and load that plugin with JMeter to use it. Or encapsulate the logic into something like a Java class and access that through Beanshell, etc. in the pre/post processor or sampler, etc. It provides somewhat less control of everything than some other tools like Gatling. Or at least it requires more effort and a greater level of understanding of the workings of JMeter internals than a normal user has.
- Test plan reuse - by design JMeter doesn't work very well when you have frequent components that you reuse across tests or having different modular tests chained together to form a bigger load tests. It gets harder to do so as you scale up with more tests or more levels of testing. Though someone once pointed out to me you can deal with this to some extent using test fragments and encapsulate the reusable component configurations in a test fragment that you can import to other tests. The fragments would be like the test templates. I've personally not gotten around to trying that out though. The other approach is to abstract the common usage functionality/code into Java class (for use with Beanshell, etc.) or JMeter plugin and reuse that. And the lazy way most beginners would deal with reuse is copy & paste from one area to another or one file to another.
- JMeter might not generate load as well as other test tools not being able to scale up the load as high. I personally have not observed this yet comparing different load tools. But our test frameworks/tools division has found that Gatling scales higher and better than JMeter for high concurrency load against the system. So just wanted to point that out.
We use JMeter to test our platform application. It is used by the whole organization.
- You can do customization for the script. I have to write a Java code for integration with two factor authentication. It is pretty straight forward with putting in customized Java code and libs.
- It is more useful for power users instead regular users. Plugin can be easily added.
- It is free and community supported.
- Reporting and analytics

Jmeter- Performance testing tool
Jmeter was used by my organization to test Java web applications. We used to prepare scripts based on the use case scenario which was performed frequently. We used to then perform load, soak tests using these scripts to analyse response time, throughput of the web application. We also used to monitor system performance like CPU, memory performance during these tests.
It is used by my department. It handles the business problems of estimating how much the application would sustain under high load, resources required for a particular client requirement.
It is used by my department. It handles the business problems of estimating how much the application would sustain under high load, resources required for a particular client requirement.
- Jmeter scripts are good to be used for load and soak tests. This helps in analysing response times and throughput. For example for a particular application it would give response time for each transaction you perform like login, submitting information etc.
- Jmeter has elements like listeners which helps us visualize results and helps us compare them. This helps in analyzing the results faster. For example to compare response times of different transactions
- Jmeter is flexible and can be used to test any applications apart from Java. For example I tried to prepare scripts for SOAP and web service.
- Jmeter requires many tweaks with respect to its configuration file and thread properties. users need to edit theses files themselves. There could be some interface where we can edit this fields.
- Jmeter cannot handle more threads and hangs up when we increase the number of threads. This causes lot of inconvenience. In these situations, user can be notified that such change would be lead to slow performance so that user can do as required. The same appears when we try to view huge files on graph listener.
- Jmeter should optimize the read and write access to output csv since it acts as overhead to the I/O performance. This affects our test results for the application which we are testing.

Performance testing using JMeter
We used JMeter as a tool for performance testing of our web application for both frontend/backend. We have configured jobs on Jenkins to execute jmeter tests on parallel. For ex. we have tried out registration performance both on Stage and Live environments in parallel with the same parameters to compare the results.
- Apache JMeter is a great tool for doing performance testing of web-applications.
- Apache JMeter also can be used for functional tests because it has a set of assertions and extractors (i.e. elements) which allow you to not only get the page from the server, but also to control its content. In this mode, JMeter saves much more information about each request (full response and request body).
- To make browser emulation more realistic, JMeter has elements which can work with cookies and cache. These elements are HTTP Cookie Manager and HTTP Cache Manager.
- JMeter uses a synchronous request approach. That means for every request JMeter generates, an internal thread is raised and therefore blocked until a response is being received or a timeout happens. This results in resource blocking on the load injector. The maximum number of threads is limited within a JVM - dependent on the underlying infrastructure - and even if you are able to run a lot of parallel threads this will result in a higher CPU and memory utilization. Although performance tweaking and scaling out to distributed testing might help in such a case, it makes testing more complex and error-prone.
- This behavior can result in distorted metrics. Think about a typical breakpoint load test. You want to determine, which is the maximum number of requests per second your tested system can serve. This will be limited by JMeter to max_requests_per_second = (1000 / average_request_time_in milliseconds) * max_jmeter_threads.
- Even if the system could serve more, this is the maximum number JMeter can inject. This is especially important when the tested application has long response cycles, e.g. because of long lasting transactions or long lasting calculations within the requests.

Performance Testing Using JMeter
JMeter is the main preferred performance testing tool in my organization. It is the best tool to test the performance of an application at the protocol level and also at the UI layer with various thread groups, listeners etc.. The BlazeMeter plugin for record and playback is also very helpful. Jmeter itself has a very neat UI. It being an open source tool makes it more and more attractive.
- It has many inbuilt functionalities like cookie manager baked in so that you don't spend too much time in addressing those. It's UI is very neat and very easy to use. Record/Playback options to build tests.
- You can easily add what thread groups, logic controllers, samplers, assertions, listeners etc.. for effective performance tests
- As a bonus, you can use JMeter to test the functionality of web services/rest services as well meaning you can use ONE tool to test performance and functionality of your service layer
- It's very easy to parameterize the tests and also load the data from excel which you would expect to do a lot in good performance testing.
- With the samplers, you can integrate selenium with JMeter to develop effective tests at UI layer for free.
- Even though it has very easy installation, you can run into issues easily. I was ab;e to trigger a test at browser level but couldn't stop the tests. I had to kill it from task manager and then had to reinstall from begining.
- There are so many things in JMeter you can do especially with the sampler for selenium for UI tests. More documentation/webinars etc.. would help the community better.
- The jmx files should have an easy way to be integrated with ci/cd tools and cloud.
Our organization utilizes the JMeter product across many areas of the IT footprint. Our application development teams will use it for unit testing and our quality assurance team uses it for functional, performance, load and stress testing. We have identified many memory leak, database connection and virtual server issues with the versatility provided by the JMeter product. Our company is expanding their horizons with SOA and other web service upgrades that were until recently an unknown environment for our testing teams. I have spent countless hours in test case and use case review with our QA teams and having Jmeter as a viable testing option has been crucial in our performance and load testing endeavors. We have identified shortcomings in our initial virtual server setup and web service breakdown through comprehensive testing and use case review.
- JMeter has the best range of 'config element' options available to the user. Versatility is the key for me when building a solid base of data options that will be available for all facets of the desired test case selection.
- JMeter provides the user with a variety of reports, results and graphs that can provide the customer with a solid picture of the overall success of the test plan and how to build out the future scenarios. The key is having all levels of output options (executive to technical) and the ability to have comprehensive reviews for all IT teams.
- JMeter has a very robust multithreading framework that allows my team to emulate dozens of user options and threads from within the same test sampling. Building a broad-based test sample is crucial to the success of our testing efforts as we step towards the SOA environment and away from the archaic way of thinking about QA testing. Too many other load testing tools are limited in their scenario building options and ability to simulate so many different types of users.
- I would like to see the WebService (SOAP) functionality returned to JMeter. I don't mind the HTTP option update for this, but I still use previous versions with this option available.
- I would like to see someone build a better, well-rounded documentation effort. I understand this is open source, but there are millions of users out there and at least one of them has some Technical Writing background.
We used this product to do graphing and on the fly reporting. It allows us to pull data and graph it without laying it out carefully every time and allows for quick information. We don't use it often but I have enjoyed being able to look at data in a graphic content.
- Easy on the fly reporting
- Graphics are easy to read
- Can be adjusted easily
- More user friendly for people not as familiar with coding
- A GUI approach
- More plain language for data

Need REST-API Automation? That's the tool to use!
Jmeter is used within our department for REST API Functional and non-functional test automation. It is fast and reliable and quite extensible, that's why we are using it. A single testing module can be made and very highly paramterized such that it would be executed many times with various parameters combinations. It is also easily integrated with Jenkins as a CI framework.
- REST API Functional and Non-Functional Automated Testing.
- Stress and Load Automated Testing.
- Highly Parameterized Test Modules.
- Excellent Integration with CI Frameworks such as Jenkins.
- Documentation is not user-friendly, you may need quite an extensive amount of time to resolve an issue.
- Post processing of page responses is not easy to understand and needs long time to learn, although quite powerful.
- Time invested to on-board the application and understand its power, and be able to learn it, can be long.
JMeter is becoming the standard across Intuit. There is still a legacy investment in Silk Performer but it is being phased out in favor of JMeter. One large organization does have its own tool but most have adopted the open source JMeter. Another tool that is seeing adoption is Gatling. JMeter is open source and free. That addresses the issue that Silk Performer is an expensive problem. JMeter does not require licenses. That addresses the issue that Silk Performer machines are a limited problem. JMeter experience is easier to find and is more relevant in today's market.
- JMeter is easy to use. Explaining how to get a simple script going is not difficult.
- JMeter is open source and free.
- JMeter really is the industry standard now.
- JMeter does not make good use of system resources. In the AWS cloud I often use 100 m1.large JMeter instances to simulate equivalent loads as 20 m1.medium Gatling instances.
- The JMeter .jmx file is hard to diff. JMeter scripts are not written as code, the user uses a GUI to create a gigantic xml file.
- When you have to drop into Beanshell things are not fun.
Hi, I use Jmeter in current company (Strevus) and used it in Oxagile to build load profile for sowtware applications and products that I was testing. Also I measured web applications response times when performing load and stress testing. Also I measure DB response times (MySQL) when loading DB with queries (selects, udpates etc.). We used Jmeter mostly in our Engineering (DEV and QA) departments
- Easy way to create and configure http(s) requests being emulated by Jmeter. A lot of configurations of http requests
- Easy way to configure and run DB load tests using connector-j library for MySQL
- Jmeter Scripts debugging mode and real time debugging when scrips are being executed help to catch a lot of application issues and helps to fix issues in load scripts
- Reporting tools and reports configuration. I would like to have configurable reports by metrics that Jmeter has
- Integration with servers statistics gathering. AFAIK Jmeter can gather load logs only from TomCat server but I would like to have more advanced integration and gathering logs from other wide spread web servers (e.g. IIS etc)
- Complex language (Java) to write your own assertions or advanced scripts that emulate non-predefined actions

Jmeter is a great automated tool that can be used for both functional and load/performance testing.
Jmeter is being used primarily to test functionality of web services for our project.
- Load Testing - it is easy to conceptualize the type of requests being made
- Plug-in support - if Jmeter doesn't come with something you need you are likely to find it on the internet. You could even develop a plugin yourself.
- Simplicity - the interface is pretty barebones and straightforward, you will not be overwhelmed by options
- It would be nice to more easily integrated into a CI system (like Jenkins/Hudson). There are workarounds out there but they are not very straightforward to implement.
- Memory usage of the tool can get high when using the "graphical" listeners in real time.

why Jmeter to use for functional and automation and performance testing
- Jmeter has a good user interface, and this is one of its best strengths.
- It supports most of testing like functional, automation and load.
- It supports any open source language like Java, Javascript, BeanShell, Groovy. Any developer can use it.
- It integrates with Selenium, Eclipse, Jenkins, TeamCity.
- As it is opensource, there could be small bugs, so if developers are throughly checked, it will be best
- One should understand of proper language, then it will be easy to use JMeter.
- it is not like commerical tool. so it wont have advantages of them
It is used for performance testing of mobile or desktop applications to check the scalability, reliability, and responsiveness of the product in the market. It is used by the performance center of excellence department inside the performance engineering team of the company. It addresses response time issues and performance metrics of applications faced by the client product.
- Open source tool
- Database load testing
- Handles the correlation effectively using regular expressions
- Naming convention of transaction scenarios in the jmeter dashboard could be improved.
- Think time and pause time could be explained effectively.
- Increase the RAM usage from tool itself rather than going into the bit files and changing it for accommodating a higher number of users and machines.
- Limited access to help
- Improve GUI of tool

JMeter good to use for API /performance testing.
I am using JMeter for API testing. I designed a data-driven API testing framework with JMeter, which is very helpful for testing APIs as well as setting up some performance tests. I integrate JMeter with Jenkins. It helps our company a lot for performing and managing the API test. And it is easy to set up a performance test system. I have helped my company set up a lab with continuous load testing to measure the performance of our product, as well as setting up an automation performance testing system and shipped it to some of our customers.
- Data-driven api testing framework.
- Performance testing.
- Easy Integrated with Jenkins.
- When designing API testing with JMeter, the thread hold is very limited.

You need to try JMeter! I have and I don't regret it.
We use JMeter in our company to test load and performance of our web sites. Our scripts leverage the flexibility and ease of use of JMeter to test the different pages of our websites and generate dynamic content requests. We hired the services of BlazeMeter to leverage their infrastructure to run the test in different regions and different concurrent user configurations to our different regional pages.
- Easy to use and parameterize.
- Can be executed from command line, so it can be easily plugged in with continuous integration tools like Jenkins.
- The script is contained in an xml file, so it's portable.
- It's free.
- UI is not very robust.
- Poor graphics and reports.
- Not very intuitive grouping of the tools, steps and plugins. Some are difficult to find, especially the first time you use it.
In our company we use JMeter for our regression tests, also for simple cases such as sign up, log in, etc. It helps us to save a lot of time for some testing cases that should be done every day, so we have created some tests and are running them daily. In our IT company this tool is used mostly by QA team.
Sometimes it helps us to find problems that we could miss. So I hope to work with JMeter as long as it is possible :)
Best Regards,
Narine.

- Easy to use.
- Fast.
- As I'm not an expert, I can find almost everything I need to work with.
- Possibility to revert wrongly deleted fields.
- Copy/Paste functionality is working not for everything.
- It would be better to improve design, it looks a little bit outdated.
