Performance and load testing

k6 and JMeter scenarios for peak traffic, soak tests for memory leaks, application and database profiling, baseline metrics before and after optimization.

Most companies discover their system cannot handle peak traffic only when Black Friday or a product launch hits — and by then it is too late. We build realistic load-test scenarios from your production logs, simulate peak on a staging environment, and find bottlenecks before customers do. After tuning, the tests stay — as a continuous check that every new release does not blow the performance budget.

What we deliver

  • A realistic load test scenario derived from production access logs
  • Peak traffic tests (target: x2, x5, x10 of average load)
  • Soak tests (24h+) to surface memory leaks
  • Application profiling (Node.js inspector, py-spy, pprof) and database profiling
  • Top 5 bottleneck identification with impact estimates
  • Optimization implementation with before/after metrics
  • CI integration — performance budget that blocks regressions

When to call us

  • You are preparing Black Friday, a product launch or a major campaign
  • The system falls over at peak hours and nobody knows why
  • You need capacity planning for the next year
  • You are migrating to new infrastructure and want to know before cutover

How we work

Discovery of real load from logs → test scenario development → execution on staging with monitoring → bottleneck identification → optimization implementation → rerun for validation.

Frequently asked questions

k6 for most modern projects — JavaScript scripts, fast feedback, good Grafana integration. JMeter when you work with unconventional protocols or have a big legacy JMeter investment.
