Performance testing types

There are several performance testing types, each revealing unique insights—whether it's handling traffic spikes, large data volumes, or long-term load. Together, they ensure your app is fast, stable, and ready to scale.

Stress testing

Measure how your system behaves under extreme conditions and identify breaking points.

Load testing

Evaluate performance under expected user loads to ensure smooth operation.

Volume testing

Test how your application handles large volumes of data without performance loss.

Endurance testing

Assess stability and performance over extended periods of sustained load.

Recoverability testing

Verify how quickly and effectively your system recovers after failure.

Spike testing

Simulate sudden traffic surges to ensure your app can handle rapid load fluctuations.

FAQ

Most popular questions answered

Performance testing evaluates how your software behaves under various conditions, such as heavy load, high user traffic, or limited system resources. It's crucial because a product that works fine with a few users may slow down or crash with many users. By doing performance testing, you ensure your application meets speed, stability, and scalability requirements. This is especially important for user satisfaction: a slow or unresponsive app can drive users away. In essence, performance testing helps you deliver a fast and reliable application experience by identifying bottlenecks before your users do.
It's wise to incorporate performance testing during critical milestones of your product's growth. For example, before a major product launch or marketing campaign (when you expect a user spike) is an ideal time – this lets you verify the app can handle the load. You should also do it if you've noticed slowdowns in development/staging or received feedback about slowness. Additionally, after significant changes (new features or infrastructure changes), performance testing ensures no regressions in responsiveness. Essentially, if you're planning for more users or see any signs of slowness, it's time to perform performance tests.
TestDevLab provides a range of performance testing types to cover different scenarios. We conduct load testing to check how your system handles expected user volumes, stress testing to determine its breaking point under extreme load, and endurance (soak) testing to see how it performs over extended periods. We also perform spike testing (sudden bursts of traffic) and volume testing to examine how large amounts of data affect performance. By covering these various test types, we can pinpoint performance bottlenecks and ensure your application remains stable and fast under all conditions.
We use our custom-built tool Loadero to mimic real-world usage as closely as possible. For example, we generate real users to simulate thousands of concurrent customers using your app. We also incorporate network condition simulation – testing under different bandwidths or unstable connections – to see how the app behaves on slow networks. Our engineers examine CPU and memory usage, database performance, and even factors like battery consumption under load. By testing with these real-world variables (including using real devices when needed), we ensure the performance results accurately reflect how end-users will experience the product.
A well-performing application greatly enhances user experience. Performance testing helps eliminate issues like long load times, app freezes, or crashes – all of which frustrate users. By fine-tuning your app's performance, you ensure that even under high usage, users get smooth and fast responses. This leads to higher user satisfaction, better retention, and positive reviews. Additionally, a performant app can handle growth in user base without degradation, which is critical for startups aiming to scale. In summary, performance testing safeguards the speed and reliability of your product, directly contributing to an excellent user experience.
We take data protection seriously. Every project starts with a mutual NDA, and we follow strict in-house security protocols, including ongoing staff training. Our ISO 9001, ISO/IEC 27001, and ISO 22301 certifications reflect our commitment to quality and security. Need extra safeguards? We also offer customizable, on-premise testing and enhanced security setups on demand.
