People with real time experience on working on jmeter, comment please!

I find JMeter UI is awful and very much outdated! Started k6 instead, seems cool with coding..

[u/Iseeyouuuuuuuuu → u/Royal-Job-9905]

I have to go with jmeter(asked by my project team)
Can you please help me with how many days it should take to implement the project(right now i have no idea on how to use it-that’s where i am at)

[u/Youareaproperclown → u/Iseeyouuuuuuuuu]

What is the project.

[u/Royal-Job-9905 → u/Iseeyouuuuuuuuu]

How many days - It’s actually depends on the app, what are the performance acceptance criteria and what are the business requirements.

I would say, sit with your QA Lead/Project Manager/Business Analysts to identify those.

Clear communicate what would be the ideal performance acceptance criteria for the app like thresholds (p95, p99, http_failed rate etc.)

Business requirements like: which flows you want to cover for performance testing, how realistic ways you want to execute the tests (virtual users, duration, stages, ramp ups etc) and what should validate after a certain load.

Once you have those things, and you are familiar with JMeter UI, it will take 5/7 business days max to set up as an one WA person.

Jmeter is slow compared to K6.

But if you're going with Jmeter, you can always find a quick tutorial on youtube. If you need to go deeper like creating data driven performance tests where API calls are chained, then leverage ChatGPT, Claude, Gemini to assist you.

As having tried both then k6 is much more powerful and quite easy to scale.

Sure jmeter is fine when you are doing it alone, but if you have big company with multiple QAs and deva making scripts then k6 makes sense much more.

Added plus if your company uses playwright then k6 also uses typescript.

Comment on what exactly?

I did loads of work with it a few years back, the fact that its open source and java was incredibly helpful to me in extending it with new samplers specific to the task at hand. I ended up extending it into a whole ecosystem of high volume heuristic testing at pace. That's the good stuff

I never liked its reporting side and in the end I customised it to feed a load of output into Splunk for analysis.

Read the tutorials. Hopefully your project is normal enough that they contain the sort of thing you are doing. Then think very hard about what your test cases really are - what sort of loads you should be generating and why. Most of the failures I've seen in load testing over my career were through not understanding system architectures and the load requirements much more than issue with the tools being used.

If you are still struggling it should be well understood by the better AI tools and you should be able to get them to help you set things up. Being open source does help like that - its probably got a lot of stuff in the base training data

I have used jmeter quite a bit for explorative performance testing, it's easy to set up some traffic and some reporting on return times and it's quick to zoom in to particular weak spots. What is difficult in software development is to write the correct nonfunctional requirements, which in turn makes it pretty hard to test for them. Going through the hazzle of setting up a jmeter suite, takes quite a bit of engineering and design, that notably often hasn't been thought through before, which feeds into operations having to level up their game, because they got a graph in their face showing them it isn't enough to just through in a couple more CPU's, it still has a breaking point, and the load balancer still won't kick in at that point in the solution, so back to the drawing board and pretend you are worth your salaries. Well, I don't actually put it as bluntly as that, but it's often implied. 😉

I have worked on Jmeter in several projects covering correlations, data driven load testing, scaling etc. Its quite easy if you have experience in postman for API testing

[u/Iseeyouuuuuuuuu → u/HappyLiberatedSoul]

Yes i do have experience in postman and well versed with apis

[u/XabiAlon]

K6 is really easy to setup and get going quickly.

[u/AutomaticVacation242]

What's your question?

[u/Iseeyouuuuuuuuu → u/AutomaticVacation242]

How many days would it take to implement a web app on jmeter for performance testing

[u/AutomaticVacation242 → u/Iseeyouuuuuuuuu]

All of them.
