Performance testing

Performance Testing

Make sure your applications remain fast, stable and scalable, even under peak load. With targeted performance testing, we identify bottlenecks, optimize response times and ensure that your software continues to perform when it really matters.

Reliable performance, with no surprises

A slow or unstable application costs users, revenue and trust. With performance testing, we identify risks early on and ensure that your systems continue to perform under all circumstances.

We analyze how your application reacts under different loads, identify bottlenecks such as slow processes and memory leaks, and provide concrete insights to structurally improve your performance. This is how you build software that not only works, but also keeps on working.

Identify your application's bottlenecks

When is performance testing relevant?

Performance testing becomes essential as soon as stability, scalability and user experience come under pressure.

peak load expected (e.g., campaigns or events)
Are unsure about the scalability of your application
Experiences slow response times or timeouts
Want to release new features without performance risk
Want to get a handle on infrastructure costs

What we test

We combine different types of performance testing to get a complete picture of your application's performance. This way we detect not only problems, but also opportunities for growth.

Load testing

With load testing, we determine how an application performs under a realistic and constant load. This gives us insight into response times, stability and bottlenecks within the system under normal daily use.

Stress testing

In stress testing, we examine how the application responds when the load exceeds normal limits. With this, we map the maximum capacity and behavior under extreme conditions.

Spike testing

Spike testing shows how an application handles sudden, strong spikes in traffic. Think of many users logging in at the same time, where stability and error handling are crucial.

Scalability testing

With scalability testing, we analyze how well an application grows with increasing usage. By simulating future growth, we assess whether the infrastructure remains easily scalable.

Endurance testing

Endurance testing focuses on long-term loading over an extended period of time. With this, we detect memory leaks, performance degradation and other problems that only appear over time.

Capacity testing

During capacity testing, we determine the application's breaking point by incrementally increasing the load. This helps to optimally tune resources and infrastructure.

Trend monitoring

With trend monitoring, we continuously track application performance over time. In this way, we identify deviations early and prevent unexpected performance problems in the future.

Our approach

We use a structured and data-driven approach to analyze and test the performance of your application so that you can optimize in a targeted way. From initial analysis to concrete improvement actions, we ensure maximum impact and minimum risk.

1. Analysis & intake

Together we determine critical user scenarios, performance objectives and KPIs. We identify risks and align the testing strategy with your business.

2. Test strategy & design

We design realistic test scripts and scenarios, tailored to your application and architecture. Here we take into account peak load, growth and integrations.

3. Implementation & monitoring

We run performance tests and monitor real-time metrics such as response times, throughput, CPU and memory usage.

4. Reporting & optimization

You will receive clear reports with bottleneck analyses and concrete recommendations. We help you not only find problems, but also solve them.

What does performance testing provide?

Faster applications and better user experience

Reduced downtime and production incidents

Higher conversion and customer satisfaction

Understanding scalability and growth opportunities

Lower infrastructure and support costs
