Performance Test Strategy & Planning
Performance testing strategy covering workload modelling, user journey prioritisation, SLA definition, environment planning, test data strategy, and tool selection. Designed to deliver actionable performance risk insights aligned to business-critical scenarios, release objectives, and infrastructure constraints.
Load Testing
Load testing using production-informed user volumes, transaction rates, and concurrency levels to validate SLAs, response times, throughput, error rates, and resource utilisation. Scenarios are based on real traffic patterns and critical user journeys, providing reliable evidence of production readiness.
Stress Testing
Stress testing through progressive load escalation identifies system breaking points, bottlenecks, degradation patterns, and recovery behaviour across application, database, cache, messaging, and integration layers. Results provide capacity limits and evidence for infrastructure, scalability, and architecture planning.
Endurance & Soak Testing
Soak testing under sustained load for 8–72+ hours identifies memory leaks, resource exhaustion, cache saturation, database contention, and long-term performance degradation. Ideal for continuous-operation systems where stability, resilience, and sustained performance are as critical as peak-load capacity.
Spike Testing
Spike testing simulates sudden surges in user demand to validate auto-scaling, load balancing, CDN performance, database elasticity, and queue management. Ensures systems can absorb unexpected traffic events without service degradation, instability, or user-visible failures.
Volume Testing
Large-volume data performance testing for bulk imports, batch processing, reporting, exports, and ETL workflows. Validates system behaviour at production-scale data volumes, identifying query bottlenecks, indexing limitations, processing thresholds, and long-term scalability risks before they impact operations.
API Performance & Microservices Testing
API and microservices performance testing measuring latency, throughput, error rates, and payload processing under isolated and integrated load. Identifies service bottlenecks, dependency constraints, and latency amplification across call chains, providing component-level insights for performance optimisation and scalability planning.

FAQs on Performance Testing Services
Have a question? We’re here to help.
Performance testing is the broader discipline used to evaluate how a system behaves under varying conditions. Load testing validates performance under expected user volumes and transaction levels, ensuring response times and reliability meet business requirements. Stress testing pushes the system beyond normal capacity to identify breaking points, bottlenecks, and recovery behaviour. Other performance testing types, such as spike and endurance testing, assess how systems respond to sudden traffic increases and prolonged workloads.
We build workload models based on real user behaviour wherever possible, using production traffic data, application logs, analytics, and monitoring tools to understand transaction volumes, user journeys, session patterns, and peak demand. For new systems, we model expected usage from business requirements and user workflows. This ensures performance tests accurately reflect real-world conditions and provide reliable insights for capacity planning and risk reduction.
A valid performance testing environment should closely mirror production in application configuration, architecture, integrations, and infrastructure behaviour. While hardware resources can sometimes be scaled proportionally, key components such as databases, caching layers, load balancers, and external integrations should reflect production conditions as accurately as possible. The closer the environment matches production, the more reliable and actionable the performance test results will be.
We use a tiered approach to performance testing within CI/CD pipelines. Lightweight performance checks run on every code change to detect regressions early, while more comprehensive load and stress tests are executed in staging environments or before major releases. Performance budgets for response times, throughput, and error rates can be enforced as deployment gates, ensuring performance issues are identified before production without significantly impacting release speed.
The number of virtual users should reflect your expected peak concurrent users, not total registered users or overall traffic volume. We determine this using production analytics, usage patterns, session duration, and business projections to model realistic demand. Accurately simulating peak concurrency ensures the test exposes performance bottlenecks, resource contention, and scalability limits that may only appear under real-world load conditions.
Performance issues discovered near launch should be prioritised based on business impact, risk, and remediation effort. Critical failures that prevent the system from supporting expected user demand should be resolved before release, while lower-risk issues can be assessed, documented, and scheduled for post-launch remediation. We provide clear performance data, risk assessments, and remediation options to support informed launch decisions rather than relying on a simple pass-or-fail outcome.
We assess each third-party integration based on the testing options available. Where vendors provide performance testing environments, we test against those systems directly. If production testing is permitted, we coordinate load volumes and timing with the vendor. When neither option is available, we use service virtualisation or API stubs to simulate external dependencies while documenting any remaining performance risks. This approach enables realistic performance testing while protecting vendor relationships and minimising operational risk.
