Performance & Load Testing
Your app works fine with 10 users. But what happens when 10,000 hit your checkout page on launch day? We find the answer before your users do. simulating real traffic, finding bottlenecks, and telling you exactly what to fix.
You won't know where it breaks until it breaks. unless you test first
Every app runs fine in staging. Then Black Friday hits, or you get featured on Product Hunt, or a marketing campaign drives 50x the usual traffic. and suddenly your checkout is timing out, your database is at 100% CPU, and your users are seeing error pages. You find out your app can't handle the load at the worst possible moment.
We find those breaking points before launch. Using K6 and JMeter on distributed AWS infrastructure, we simulate real traffic patterns. ramp-ups, sudden spikes, sustained load over hours. and watch exactly what happens to your response times, error rates, and server resources.
You get a detailed report showing where the bottlenecks are, why they happen, and what specifically to fix. After your team makes the changes, we re-test to confirm the improvement. No guessing. No hoping. Just data.

How We Actually Work
No black box. Here's exactly what happens from the first call to a fully running test suite. and what you get at each stage.
We define what "fast enough" means for you
What response time is acceptable? How many concurrent users do you need to handle? What's the error rate threshold? We set clear performance SLAs before writing a single test.
We design load profiles that match reality
We don't just throw random traffic at your app. We model realistic patterns based on your actual analytics. peak times, geographic distribution, user behaviour, and worst-case scenarios.
We set up the test infrastructure
K6 or JMeter running on distributed AWS instances, Grafana dashboards for real-time monitoring, and a test environment configured to mirror production as closely as possible.
We run the baseline and find what's already slow
The first test establishes your current performance baseline. This often reveals bottlenecks you didn't know existed. slow queries, memory leaks, unoptimised API calls.
We push it until it breaks
Spike tests, stress tests, soak tests. We find your application's breaking point, test how it recovers, and validate whether your auto-scaling actually works under real pressure.
You get a report, fix it, we re-test
Every bottleneck documented with specific file/query references, resource utilisation graphs, and remediation recommendations. After your team fixes the issues, we run the tests again to verify the improvement.

Got questions?
Here are the ones we get asked most. If yours isn't here, just ask. we're happy to talk it through.
Want to talk through your specific setup?
We'll walk you through how this works for your stack, team size, and release cadence. zero commitment.
Up to 100,000 concurrent virtual users using K6 and JMeter on distributed AWS infrastructure. The practical limit depends on your app's architecture and what we're trying to measure.
