Performance failures rarely announce themselves in advance. They surface during a launch, a flash sale or a traffic spike — exactly when slow responses, timeouts and cascading outages do the most damage to revenue and reputation. We bring the same adversarial mindset we apply to security: model realistic and worst-case load, then deliberately drive your applications, APIs and infrastructure past comfortable operating conditions.
Our engineers build scenarios from real user journeys and production traffic patterns and execute them with industry-standard tooling — k6, JMeter, Gatling and Locust — instrumented end to end. We don’t just report a number; we trace latency through the stack to the responsible component, whether that’s an unindexed query, connection-pool exhaustion, an N+1 pattern or a downstream dependency that buckles under concurrency.
You get a clear, prioritised picture of real capacity — where the system degrades, where it breaks and what it costs to scale — plus reproducible test suites and hard baselines you can stand behind in your SLAs. (This pairs naturally with the performance and security audit we delivered for clients such as Printful.)
How it works
- 01
Scoping & modeling
Objectives, SLAs and success criteria; analyse production traffic and target load profiles.
- 02
Test design & instrumentation
Realistic scenarios in k6/JMeter/Gatling/Locust; representative environment; metrics and tracing.
- 03
Execution & analysis
Load, stress, soak and spike runs; capture latency percentiles, throughput and error rates.
- 04
Bottleneck diagnosis & reporting
Trace failures to root cause across app, database and infrastructure with reproducible evidence.
- 05
Remediation & retest
Support fixes and tuning, then re-run to verify and set new baselines (optional).
Packages
