Stress Testing
Your application can run perfectly under normal conditions and collapse on the day you need it most. We simulate that scenario before your users do — with realistic load, precise metrics and a report that speaks both to the technical team and the business.
Who is this service for?
If you're about to launch a critical feature, if your system has already had an incident under peak demand, or if you simply don't know how many concurrent users your app can handle — you need a stress test before finding out the hard way.
What do we analyze?
Realistic load simulation
We design scenarios based on your historical or projected traffic. We don't simulate fake users — we simulate your real user base.
Server monitoring
We track CPU, memory, response time and error rate in real time throughout the run.
Bottleneck identification
We pinpoint exactly where and why your architecture starts to fail, before it reaches production.
Executive and technical report
A detailed report with findings, performance metrics and concrete optimization recommendations.
What we find matters
On tests for Fintech and Banking clients, we detected services that started degrading minutes into the load, with latencies above 40 seconds when the target was 1 second, and HTTP error rates as high as 42%. All of it caught in staging — before it ever reached production.
Why Qualis Lab?
Experience under heavy demand
We work with Fintech and Banking companies where load peaks aren't optional — they're the business.
Tailored scenarios
We configure the test against your real traffic, not generic templates.
Industry-standard tooling
JMeter, K6 and Locust depending on the case, choosing the right tool for each architecture.
Flexible delivery
We work in staging without touching production. Remote across Latin America, on-site in Argentina and Uruguay.
Frequently asked questions
Before a launch or high-demand event, after an incident in production, or as a periodic practice to validate that your system scales with the business. Any of the three is a good moment.
