Why you should do performance testing
Performance tests check how a system, application, or website behaves with a large number of users online. They help detect performance bottlenecks, errors, and potential failure points even before production deployment. All to ensure stability, speed, and a positive user experience, directly impacting customer satisfaction and your competitive advantage. Regular performance testing minimizes the risk of downtime and financial losses, and supports IT infrastructure planning and effective system scaling.
What we can help with
Compliance with DORA
and NIS2 regulations for digital resilience and incident reporting.
Early detection of load problems during the software development phase.
Handling large traffic spikes, e.g., during Black Friday or other sales peaks.
Obtaining an independent, reliable opinion on system performance.
Detecting and removing
system bottlenecks that affect stability and speed.
Performing simulations to obtain reliable data on system behavior
under load.
Planning migration to a new system, software, or the cloud while maintaining business continuity.
Ensuring a positive first-time user experience when launching an application on the market.

Types of performance tests we do
Load testing
Detect bottlenecks and check your system's response times when loaded with the expected number of users.
Overload testing
Verify your system's response to overload by exceeding the standard number of users at once.
Long-term load tests
Check whether the system is stable under constant, long-term load.
Surge load testing
Simulate a sudden increase in system users to test its performance under extreme conditions (e.g., on Black Friday).
Volume testing
Verify how long it takes and how much data the system can accept.

Why invest in professional performance testing?
Professional performance tests allow you to answer key questions that directly impact the stability, scalability, and cost-effectiveness of your systems:
Are the infrastructure costs adequate for the user load being handled?
Will a new feature negatively impact on the performance of the entire app?
What’s the maximum traffic that our IT environment can handle?
Testing early in the system lifecycle helps identify bottlenecks faster – and these often result from architectural assumptions. Correcting these assumptions early on is especially important with newly created systems, where the bug-fixing costs increase significantly as the project progresses.

FAQ
- Load testing – check system performance under expected traffic
- Overload tests – see your system's limits and how it behaves when they’re exceeded
- Performance tests – verify response times, stability, and resource consumption.
- the number of concurrent sessions,
- how the application is used (scenarios),
- traffic files, not average values.
- you can see that it is slow,
- but you don't know why.
- get to know the application and how it works
- prepare business scenarios
- validate the application's behavior under load
