Apache JMeter is an open-source Java application that tests load and functional behavior and performance in applications. Created initially to test web applications, it has expanded its functionality to test other functions. For instance, you can test a server to see how efficiently it works and how many user requests can be handled simultaneously.

You can use JMeter to test functional performance and regression tests on different technologies. This Java desktop application has an easy-to-use graphical interface which uses the Swing graphical API. You can run JMeter on any environment that accepts a Java virtual machine, such as Windows, Linux, and Mac.
What protocols does JMeter support?
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.

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.”
Apache JMeter was previously known as JMeter.

I've used JMeter in conjunction with Selenium, Java, and Log4j for logging. I used it before
I ended that contract in August. Its version was up to date at that time.
It was used for an e-commerce site that is specialized in C-PAP or weaving machines in effect. Their max was a thousand people logged in at once. I, of course, pushed the boundaries on that, but it was to test the performance of the website, and of course, I'm had to try subsystems, database interactions, etc.
I'm a total geek, so I liked the fact that I got to program. The biggest thing I liked about it is that there is a huge user base out there, and being shareware and being Apache, if I have any question on how to get something done, I get 18 different answers. Out of those, there would be at least a few good approaches for what I was trying to do. So, the support system out there is most valuable.
I sometimes found the documentation to be not as explanatory as I would've liked it. In the cases that I can think of, I was looking for a rather hand-holding approach with Step A, B, and C, but then I realized that with a product that is open source like this, you can't do handholding. That is because there are so many different uses and different unique environments and setups for it, but I remember thinking a few times that if they only just said this.
If I were going to be Mr. Selfish and say anything I want, I'd say a full feature GUI that lets me drag and drop different modules in line. It could have a simple-to-use GUI.
I have been using this solution for probably a year and a half.
I didn't have any issues with the stability of JMeter itself. There were definitely issues with the program I was testing, but that's why I was testing it.
It was very easy to scale, but I was barely scratching the surface. I have spent 17 years at Microsoft, and for the performance testing that we did there, we had 8.3 million users at once, as opposed to a maximum of a thousand. If I'm scaling, I have to do it quite straightforward and simple, but it was very minimal.
Only I was using it. It was the QA department. I showed it to some of the devs, and they were very interested. A couple of them tried it, but none were actually using it day-to-day for testing out the environment.
I would rate them an eight out of 10 because sometimes, they would take two or three days to get back to me. Of course, at that point, you're like, "I need the answer; I need to answer." So, it was a little bit unrealistic in terms of expectations.
At that particular company, I was the one who was tasked with coming up with the solution, so that was the only one that I looked at simply because JMeter is industry standard, but at Microsoft, they wrote their own custom tools, so I used custom Microsoft tools.
It was rather complex. It is a complex product, but that part of it was very well-documented. I didn't have any problems with it.
Don't be shy in asking questions. Google/Bing is your friend. It is complicated. There's no reason to spend eight hours trying to figure out something, except unless you are trying to learn in-depth. There are a lot of people who've done exactly what you're trying to do, and it doesn't matter what it is.
I would rate it a 10 out of 10 because it is industry standard. It did everything I could've asked. I barely scratched the surface, but what I needed it for, it did well and in a very straightforward-to-implement way.
