(1-21 of 21)Companies can't remove reviews or game the system. Here's why
Apache JMeter helps ensure our performance targets are met for release, and quantifies changes we make in the name of performance. Without it, we end up with custom code written by system testers or QA that don't always fully understand how code evolves, and then inevitably we have to throw it away in a year. Apache JMeter allows developers to run standardized performance tests ahead of QA.
- Easy to get started with
- Good, straightforward UI
- Deep options for fine tweaking under uncommon scenarios
- Some options are arcane and misleading
- Results are too easily skewed by poor methodology
Apache JMeter helps our team in areas like load testing and performance benchmarking of APIs across products and services. Every new feature that gets released is the first load tested using Apahe JMeter, by passing appropriate parameters to check if it can handle the list and stress easily. This helps to assert that the service can easily serve 'x' users in 'y' conditions. With teams focusing more on microservices and agile development, non-functional testing plays a vital role. Apache JMeter is an open-source tool written in pure Java, making it the most preferable option for us to test our services, both API and UI through its user interface as well as Non-GUI mode. This makes the SDET team perform testing and feature releases more confidently with optimum quality.
- Report generation.
- Multithreading
- Log debugging and sampling.
- Optimize CPU and Memory utilization.
- Reporting visuals and metrics.

Performance Testing made Easy!
In my organization, JMeter is mainly used by the quality department to conduct all types of performance tests. The application is very powerful and has many features. The best part is the fact that it's for free. The Application helps us deliver software products that can withstand a huge load of users which results in better customer satisfaction. You can do stress testing, load testing on both Web UI Applications and API WevServices. Also, you can read the test data needed from external Excel CSV file which helps if you want diverse load tests.
- Open Source and For Free
- Supports all types of Performance Testing (Load Testing, Stress Testing, etc.)
- Supports Web UI and API Services
- Read Test Data from Excel File
- User Interface and User Experience is very poor
- No HTML Reports generated for the Performance Test Results
- Almost impossible to edit recorded test scenarios and you need to Record the Test Scenario again
- Need to have Programming skills because most probably you will need them in Complex Test Scenarios

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.

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.

JMeter Review
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

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 Review - Tool that can used for any project type.
We use JMeter for load and stress test for most of our client's products. We target for:
- Page load
- Duration of test in seconds with number of virtual users that server can support in x number of seconds (users/sec)
- Determine a system's behavior under both normal and anticipated peak load conditions
- Min/Max duration for each page to load
- Reverse stress test and its consequences
- Duration of test in seconds with number of virtual user that server can support in x number of seconds (users/sec)
- Determine a system's behavior under both normal and anticipated peak load conditions
- Min/Max duration for each page to load
- Better UI
- Multiple project window
- Saving and importing script on another machine looses some settings

Cool open source tool for WebService Performance testing
JMeter is being used as secondary tool at our organization, in my team its primary tool though. At the organization level we use NeoLoad which is more user friendly compared to JMeter. JMeter helped us to test our services in a cost efficient manner. We deal with millions of SOAP messages and JMeter helps us to distribute and measure performance of all those services.
- Interaction with Java and JUnit is the one of best features and strengths of JMeter.
- Bean shell is another strength where you can write a customized version of your scripts.
- Webservice Performance is pretty easy compared to other tools.
- UI Recording gives a easy way of building scripts.
- JMeter needs to improve the interface and the start and stop process; several times it just hangs when you see an issue and stops testing in between. There is no impact but user has to reopen JMeter as the earlier session still hold resources.
- More powerful reporting and listeners, compare previous test and current test results. Loadosophia is best example of it, including BlazeMeter which are paid versions.

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 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.

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.

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.

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.

We use JMeter to load test restful web services. It was a little tough to get the initial setup done, but once you are past that hump, it becomes much easier to use. We were able to use JMeter to diagnose a memory leak and prove to management that we had resolved the issue, and not just making a wild shoot in the dark. Now that we have all of our basic uploads setup and configured, it only take 10-15 minutes to set up for a new test. We haven't had as good of luck with using this to load test HTML webpages, but we are still working through those issues. Overall, we are pleased with JMeter.
- Restful web service load tests - some what complex to setup, but easy to use once it is.
- More real world examples to help with learning the product
- Easier setup to load test HTML pages
- Not particularly suited for Functional 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.

I used Jmeter directly to load test a web UI in a previous role and my current employer uses it in their QA department. The main thing I love about it is that it does such a unique job of operating in a way that enables people with a diverse range of skill sets to get what they need out of it. If you just want to run a test that someone else created and analyze the stats, you just need to drop a file and you're good to go. At the other end of the spectrum, if you're building a test and want to get very specific about the test's behavior, you have a massive array of tools at your disposal. I recommend it strongly to anyone doing GUI testing.
- Modular test construction
- Detailed statistical reporting
- Exportable test design
- The level of detail it provides can be overwhelming at times for newbies. It would benefit from some improvements that made it easier to quickstart
