Performance & load testing
Systems that behave beautifully in testing routinely collapse the first time real traffic shows up. We simulate that traffic first - realistic patterns, pushed past your expected peak - so you know where the limits are, why, and what to fix while things are still calm.
Service details
At a glance
- Load and stress testing against realistic traffic
- Bottlenecks identified with likely causes
- Failure modes understood, not just thresholds
- Capacity numbers and scaling guidance
Limits are cheap to find and expensive to discover
Every system has a breaking point; the only choice is whether you meet it in a controlled test or during a product launch. Testing in advance turns a crisis into a work item - the bottleneck gets a ticket instead of a war room.
Realistic, then ruthless
Synthetic best-case traffic tells you nothing useful, so we model load on how your system is genuinely used - the spiky, awkward, logged-in kind - then push to the peak you expect and past it. How it fails matters as much as when: a system that degrades gracefully under pressure is a different animal from one that falls over hard, and you should know which one you own.
- Traffic modelled on real usage patterns
- Tested to expected peaks, then beyond them
- Graceful degradation checked, not assumed
Numbers you can plan against
You get the capacity limits, the bottlenecks ranked with their likely causes, and specific guidance on what to fix first. If you want the fixes made rather than just described, we can do that too - and retest to show the difference.
Frequently asked questions
- When should we do performance testing?
- Before anything that concentrates traffic - a launch, a campaign, the seasonal peak - and periodically as the system evolves, because last year’s headroom quietly shrinks.
- How do you make the test realistic?
- We model traffic on observed usage rather than a synthetic best case, then push beyond the expected peak - so you learn what happens at the edge, not just near it.
- Do you just find problems or help fix them?
- Both if you want. The report stands alone, but we can implement the fixes and retest to confirm the gain.
- What if the system fails the test?
- Then the test has paid for itself - you found the limit safely. We work out why it failed and what to change so it holds when it matters.
