Performance problems are architecture problems discovered too late. By the time response times climb in production, the fix usually involves significant rework under pressure. We help teams find and fix performance issues before users do.
What we deliver
Load model design. We work with your team to understand real user behaviour and translate it into realistic load profiles. This means analysing production traffic patterns, identifying critical user journeys, and building test scenarios that reflect actual usage - not synthetic benchmarks that prove nothing.
Load test execution. We run graduated load tests that methodically find your system's capacity boundaries. Starting from baseline measurements through to stress testing and soak testing, we map the full performance envelope and identify exactly where things break down.
Bottleneck analysis. Response times are symptoms, not causes. We correlate application metrics, infrastructure telemetry, database query performance, and network throughput to identify root causes. The deliverable is a prioritised list of specific, actionable fixes - not a generic report.
Performance tuning. Where appropriate, we implement fixes directly: query optimisation, connection pool tuning, caching strategies, async processing, resource right-sizing. We measure the impact of every change.
Continuous performance testing. For teams that want ongoing performance visibility, we integrate load tests into CI/CD pipelines with automated regression detection.
Tools and approach
We primarily use k6, Gatling, and Locust for load generation. For infrastructure monitoring we work with whatever you have - Datadog, Grafana, Application Insights, New Relic, CloudWatch. The tooling matters less than the methodology.
We test against environments that mirror production as closely as possible. If your staging environment has half the resources and a tenth of the data, we'll flag that before we start - results from unrealistic environments are misleading.
Typical engagements
A pre-launch performance assessment usually runs 2 to 3 weeks. Ongoing performance testing retainers are typically a few days per month. We scope every engagement individually based on system complexity and goals.
