Performance & Load Testing

Find the breaking point nbefore launch day does.

We load-test and stress-test your systems against real traffic targets — checkout flows, APIs, launches — so you know exactly how much load your system handles before it matters. Senior performance engineers, fixed scope, numbers you can actually plan capacity around.

— What we build

Four ways we test your system's limits.

From a targeted API load test to a full pre-launch capacity plan, we test against the traffic numbers that actually matter to your business. (Need the architecture fixed based on what testing reveals, or the infrastructure itself designed? See our Scalable System Architecture and Cloud Architecture & Setup pages.)

Load testing

Simulate expected and peak traffic to measure response times, throughput and error rates under realistic conditions.

Realistic traffic simulation

Throughput testing

Response-time measurement

Stress & breaking-point testing

Push the system past its expected limits to find exactly where and how it fails — before a real spike does it for you.

Breaking-point discovery

Failure-mode analysis

Extreme load

API & endpoint performance testing

Isolate and test individual API endpoints under load, so you know which specific calls are the bottleneck.

Endpoint-level testing

Latency profiling

Bottleneck isolation

Pre-launch & capacity planning

Test against your actual launch-day or campaign-day traffic projections, with a clear go/no-go recommendation.

Launch-readiness testing

Capacity planning

Go/no-go reporting

Most launch-day outages happen because nobody tested for the traffic that actually showed up.

Most “the site went down on launch day” incidents happen because load testing, if it happened at all, used generic traffic patterns instead of the numbers marketing was actually expecting. Before we test anything, we get your real projected numbers — expected users, peak concurrency, campaign timing — and test against those specifically, so the result is a plan, not a guess.

Capabilities & stack

Boring tech that
ships on time.

We test with proven, widely-adopted load-testing tools — not a custom script that only simulates traffic in one narrow way. Real numbers, reproducible on the next test run.

How we pick

01

Start with your real numbers

Before we run a single test, we get your actual expected traffic — launch projections, historical peak data, campaign targets — not a generic “test at high load” default.

02

Simulate realistic user behavior

Load tests model actual user flows — browsing, checkout, search — not just hammering a single endpoint, since real traffic doesn’t behave that way.

03

Find the breaking point deliberately

We push past the expected target to find where and how the system actually fails, so you know your real ceiling, not just whether you clear the bar you set.

04

Report bottlenecks, not just a pass/fail

Results identify the specific component that limits capacity — database, API, cache — not just a green or red checkmark.

Industries

Performance testing, tuned for
your industry.

Every industry has its own traffic patterns, peak periods and cost of downtime. We bring playbooks, not generic load scripts — and test against your organization’s real peak scenarios from day one.

Engagement models

Pick how you want to
ship with us.

Three ways in — all senior performance engineers, all fixed against the capacity target we agree on before the first test runs.

Fixed-scope

Performance baseline test

Best when you need a quick read on current capacity before deciding on a bigger engagement.

Project-based build

Best for a defined launch, campaign or capacity-planning need.

Embedded

Staff augmentation

Plug senior performance engineers into your team.

What's the difference between load testing and stress testing?

Load testing measures how the system performs at expected or peak traffic levels. Stress testing deliberately pushes past those levels to find where and how the system actually breaks. We usually recommend both — load testing tells you if you’re ready, stress testing tells you your real ceiling.

Yes — we help you define reasonable target numbers based on historical data, comparable launches, or industry benchmarks if you don’t have your own projections yet, so the test still has a meaningful target.

Both — we can isolate and load-test individual API endpoints to find which specific calls are the bottleneck, or test full realistic user journeys (browsing, checkout) that combine multiple endpoints the way real traffic does.

We model realistic user behavior — varied paths, think-time between actions, mixed request types — rather than a uniform load pattern, since real traffic doesn’t hit a system the same way every time.

We deliver a report identifying specific bottlenecks (database, API, cache, etc.) with a clear go/no-go recommendation. If you need the underlying architecture or infrastructure fixed based on findings, we can continue through our Scalable System Architecture or Cloud Architecture & Setup pages.

Early enough to fix what’s found — typically several weeks before launch, so there’s time to address bottlenecks, not just document them the week before go-live.

Yes — RAG evaluation needs to test both the retrieval step (did it find the right source documents) and the generation step (did the model actually use them correctly), since a failure in either stage produces a wrong answer for different reasons.

Yes — you own the test scripts, configuration and full results, so future load tests (before the next big launch or campaign) don’t have to start from scratch.
