Load and Stress Testing

Your system might work perfectly with 100 users—but what happens when 10,000 show up at once? Our load and stress testing services simulate real-world and extreme conditions to reveal how your applications behave under pressure.
We help you uncover hidden bottlenecks, verify scalability, and prepare for peak traffic. Whether you're launching a new product or tightening up a critical API, our performance testing ensures you’re ready for the real world—before your users find the cracks.

Tools We Use For Testing

What We Test

Load Simulation Across User Patterns 1

We emulate traffic that mirrors your actual usage—logins, API calls, database queries, and frontend behavior. This helps identify resource saturation points and transaction slowdowns as user volume rises.

Stress and Spike Testing 2

We test system resilience during sudden traffic surges and prolonged high loads. The goal: expose weaknesses in auto-scaling, error handling, and thread limits before they lead to real-world outages.

Server, Network & Backend Response 3

We analyze how backend services, databases, and network layers respond to increased demand. This includes CPU usage, memory leaks, connection pooling, and queue processing delays.

Performance Baselines and Thresholds 4

We help you define what “good” looks like by benchmarking latency, throughput, and error rates. This gives you objective metrics to track site reliability over time.

Environment & Deployment Impact 5

We measure performance across staging, QA, and production-like environments to reveal deployment-specific latency or instability. Cloud configs, container limits, and autoscaling thresholds often surface here
