Frequently Asked Questions

Book a Free Performance Consultation
What is performance testing?

Performance testing measures application speed, stability, throughput, errors and resource use under defined workloads.

How do load and stress testing differ?

Load testing evaluates expected traffic. Stress testing goes beyond expected capacity to find breaking points and recovery behavior.

What are spike and soak testing?

Spike testing checks sudden traffic changes. Soak testing checks stability during long-running workloads.

When should we run performance tests?

Test during development, before releases, after major changes and ahead of anticipated traffic peaks.

How many users should we test for?

Set concurrent users and transaction rates using traffic data, forecasts and business targets.

Do you test APIs and microservices?

Yes. Assess latency, throughput and errors under concurrent API requests and service interactions.

Which performance testing tools do you use?

Tool choice depends on architecture and load scenarios. Confirm Kualitatem’s current supported stack before engagement.

Can testing run in our CI/CD pipeline?

Targeted repeatable tests may run in CI/CD; larger tests are usually planned in production-like environments.

How long does testing take and what does it cost?

Timing and cost depend on complexity, traffic volume, environments, monitoring and retesting scope.

What deliverables do we receive?

Outputs may include workload models, result charts, bottleneck analysis, recommendations and retest evidence.
