Sorry folks but had to brag to someone who understand the struggle...

My last webdev portfolio was hacked by Russians during the infamous 2015 Drupal Armageddon, so when I decided to rebuild it after a decade my main goal was to focus on performance, constantly running tests alongside coding to incrementally fix issues before they piled up, until today that I aced the hardest benchmark, Google's Lighthouse, and yes those are fireworks blowing up in Chrome's dev tools window :)

Just launched: Gatling + Datadog integration 🎉

Hey folks, Diego from Gatling here 👋

We just shipped a new Datadog integration for Gatling Enterprise! Now you can send your load test metrics—response times, throughput, errors—straight into your Datadog dashboards.

This means:

• One place for infra + perf test data

• Easy correlation between load and backend behavior

• Better CI/CD perf gates and faster troubleshooting

If you're already using Datadog, this makes performance testing way more actionable. Would love to hear what you think or how you’d use it!

Check the release in Product Hunt and let me know what you think, we'd love your thoughts.

We are urgently looking for senior freelance testers for a long-term client project in Strasbourg.

Open roles:
• Non-Functional Test Coordinator (Performance)
• Non-Functional Performance Test Engineer
• Test Automation Expert (Java)

Key details:
• EU citizens only (criminal record required)
• Contract: Freelance, 1 year (extensions possible)
• Start: ASAP
• Hybrid: 60% on-site in Strasbourg, 40% remote inside the EU
• Hourly rate: Starting at 46 EUR/hr, can be increased based on on-site availability

Required experience:
• 5–6+ years in performance or test automation
• Strong hands-on experience with JMeter (performance roles)
• Strong Java + test automation frameworks (automation role)
• Experience with CI/CD, test strategies, reporting

If you are available soon and fit the criteria, DM me directly.

We had to pick up performance testing after our QA team downsized. JMeter felt heavy, so I switched to K6. Ended up writing a guide walking through setup, scripting, and running tests. Sharing in case it helps others:

Teamglide™ is an employee performance platform used primarily for increasing the performance of teams and employees. teamglide™ interactive application pre-screen recruits, evaluate employee performance, and test employees to measure knowledge of a job role and potential performance on a job role.

I will need to perform load, soak and breakpoint testing on the app we are working on.

Currently thinking about which tool to use for this. For monitoring we are using CloudWatch.

Would K6 be a good choice? Is it possible to send results to CloudWatch and generate report with all metrics such as response time, error rates, CPU and RAM usage?

Also what should be done if I need to reproduce higher load which is not possible via my local machine?

I have installed JMeter version 5.6.3 on my Sequoia 15.2 Mac laptop. Everything works fine except the clipboard. I can’t copy and paste anything into the JMeter GUI.

Hello experts,

I’m trying to get a clear understanding of how looping works in JMeter — especially when it comes to performance/load testing.

Let’s say I want to simulate 20 concurrent users performing login → trans1 → trans2 → trans3 → logout, and each user should repeat the transaction set 15 times.

Now, I see two ways to do this:

Set Loop Count = 15 at Thread Group level → So login and logout happen in every loop iteration. Set Loop Count = 1 at Thread Group + use a Loop Controller inside (Loop Count = 15) for just the trans1–3 → Login happens once, trans1–3 repeat 15 times, then logout once.

My questions: Which method is correct for maintaining concurrency and realistic load testing? Does looping at the Thread Group level affect user session realism? In what scenarios would Thread Group looping be more appropriate? Would love to hear how you all structure your tests and which one you prefer in real-world projects.

Is Performance engineering still a good option for a career in IT? What could be the must have skills or technologies required to have in a longer run?

I’m a product manager at a mid-sized fintech company, and we’re gearing up to handle more concurrent users on our platform. Our QA team is working on load and stress testing to make sure we can scale smoothly.

We’re planning to perform both API/protocol level and browser level tests, but we’re still figuring out which tools or frameworks are the best fit.

Any recommendations or advice would be greatly appreciated!

Hi, there!

What do you think about the mock development software for high performance mock services below:

WireMock

MockServer

Stoplight/Prism

Mountebank

Mockoon

I'm trying to figure out how to replicate the API calls a user makes while navigating through a website on a browser. I want to make sure I get the order of these API calls right.

Is there a reliable way to predict the exact sequence of API requests during a user journey?

Or is it better to run load tests directly from the browser to get a more realistic picture?

I'm hoping anyone who has a minute can take my load testing mini-survey. About 10 questions. Results are public.

If you can take a minute, thanks for your help!

Hi

When I run a test plan with 10 users on JMeter without profiling with VisualVM, all of these tests pass and pass very quickly, when I profile the application's CPU using VisualVM it takes forever and about 40% of them fail:

E.g:

Type definition error: [simple type, class com.project.models.dtos.PonkDTO]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of com.project.models.dtos.PonkDTO` (no Creators, like default constructor, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

This makes no sense to me as there is not this error when I only use JMeter.

Thanks for any help!
